TrailStar Maximus
The TrailStar Maximus pushes performance with every step. Designed for intense activity that requires speed and precision, the TrailStar Maximus functions as well in the gym as it does outdoors. These lightweight and secure sandals break the boundaries of what you expect from minimalist footwear.
Sole
The Maximus use an 8mm Vibram® Newflex sole coupled with your choice of UltraGrip or Tobacco Brown Goatskin Leather footbed for a 9mm total stack height. Vibram® Newflex is made from a blend of rubber and EVA to form a durable soling material with aggressive tread. At 3mm thicker than the Warrior sole, you will get a much more rugged sandal that is capable of diffusing the feeling of rocks, sticks, and the like from underfoot. The Maximus sole is suitable for a host of situations from the trail to the gym. Pair with the UltraGrip footbed for use in the harshest elements, or select the Goatskin Leather for more comfort in drier conditions.
TrailStar Lacing System
Increased security from over-the-foot style lacing is the hallmark of TrailStars. The TrailStar Lacing system features a specially made forefoot strap made from Toray® Ultrasuede and a nylon mesh. The result is an extremely comfortable material with the strength properties of webbing. The forefoot strap is completely adjustable and anchored through the bottom of the sole. Final adjustments are made through a tension lock on the outer heel post. All forefoot straps are cut-to-fit after adjustment. The heel section of the lacing system employs two heel posts covered in Ultrasuede for comfort. Heel strap adjustments are locked into place using Velcro®. The result is an extremely comfortable and secure lacing system that is ready for adventure!

I am in love.... had Chacko's same layout but they were heavy non flexible and imposible to correctly adjust (the "crimp" after adjusting)
Shamma are light responsive strap is soft and non abrasive. I am in love...
cheers fonty
I bought an Elite pair 6 years ago and I still wear them! This time I wanted to try the TrailStar model and I love how they look and feel. My feet are very slim and the fact that the straps are adjustable in all sections is amazing. I really hope they last as much as my previous pair!
The special pair made at the shop right in front of me by Josh!
This is my 2nd pair of sandals to be exact from Shamma Sandals.
My 1st pair was the Trailstar Alphas with ultragrip, no complain, but thinking of getting size 7.5 this time rather than 7 like the previous one and with leather too.
The fit is just spot on!
Adjustment is damn intuitive and done within minutes for both feet.
Happy Trails indeed!
First time trying these out and felt really nice. I especially love the leather footbed feel and the help with the toe splay. Easy to adjust and a great fit.

Glad I waited!
I started into my barefoot journey in early 2024. I did a lot of research into what brand of sandals to get. Shamma seemed like the perfect brand for me. I held off until November 2024 to get my first pair of barefoot sandals mainly due to price and the fact that I was traveling a lot. I have been wearing them for 2 weeks now and wow! They are a pretty good thickness, even though they are the thinnest soles. The sizing guide worked perfectly. My fit is very snuggly in them and doesn't move around, it's like a second layer for your foot. And I can run in them, how awesome! Super thrilled for my journey with ym first pair!

Best sandals I’ve ever had
I’ve tried many different hiking/running sandals over the past 10+ years, and Trailstar Maximus (ultragrip) are so far the best. For example, I tried a few LUNA sandals models, but with just 1 anchor point between the toes, the lateral movement was abysmal in more demanding terrain. My favorite sandal so far was the Xeroshoe Jessie, but it was extremely slippery in wet conditions, and they stopped producing it now. But I can’t find any fault with the Trailstars so far - very comfy, ideal sole thickness, and not in the slightest slippery even after running through deep puddles. Absolutely perfect so far!!! 👍👍👍

Best Sandal, Best quality!
I absolutely love my new trailstar sandals! The sole holds up well enough when hiking on uneven loose rock. I hiked 1400ft down and up in elevation with no problems. The comfort and adjustable fit make these sandals worth every penny!

Sizing Chart and Adjustment Guides
SANDAL SIZING CHART
We strongly recommend using the templates to check your foot size to ensure a perfect fit!
NOTE:Make sure your printer doesn’t resize or shrink to fit when printing! You can check if the templates printed to scale by measuring the printed ruler on the page with a ruler or tape measure. Larger sizes will need to be printed Poster across 2 sheets of paper. You can download the free version of Adobe Acrobat PDF Reader and print the templates in the "poster" setting. This should print to scale across two pages.
Shamma Sandals use custom soles that are designed to give you the best possible fit and experience, so please check your measurements with our sandal sizing chart. The templates of the sandals are available for download and printing.
To size yourself, print the template out and place your foot on the template so that the toeplug hole is between your big toe and first little toe. Make sure that your toes aren’t hanging off the front of the template, and that your ankles line up with the ankle slots on the sides of the sandal. If the ankle slots are under your foot a little bit, that’s ok, the laces come up and around your feet – just make sure that your toes don’t go past the front of the sandal, that your heel doesn’t go past the back of the sandal, and that the toe hole and ankle slots line up with your feet. For the best fit, we recommend choosing a sandal size that gives you between an 1/8" (3.18mm) to a 3/16" (4.76mm) of extra room in front of your toes and behind your heel. Thus, we recommend getting sandals that are 1/4"-3/8" (6.35mm - 9.53mm) longer than your foot.
If you don't have a printer, you can measure your foot according to the instructions in the video above (Episode 4) and compare those measurements to the sandal measurements on the chart above and choose a size that is 1/4"-3/8" (6.35mm - 9.53mm) longer than your foot. You can also send your foot measurements to us at contact@shammasandals.com and we would be happy to recommend a size based off of those measurements.
BOOT SIZING CHART
For boot sizing, you can generally go with your standard street shoe size.
NOTE:Make sure your printer doesn’t resize or shrink to fit when printing! Check the measuring line of the template to a physical ruler before sizing! Larger sizes will need to be printedPosteracross2 sheets of paper.

ADJUSTMENT GUIDES
Did you receive your new pair of Shammas, but looking for some extra tips on how to get the perfect lace adjustments? Look no further! Below you can find step-by-step written instructions as well as videos for how to lace your sandals!
Elite Lacing System
(Our Elite Lacing System includes Elite Warriors, Elite Chargers, Elite Maximus, Elite Alphas, and Elite Ibex).
1. First, loosen all 3 strap zones until there is excess slack in each section. The straps should be extremely loose in all three zones.
2. Start by centering your foot on the sandal, so that the placement of your foot is in the desired final location (you should have equal room in front of your toes and behind your heel with this placement).
3. Now that your foot is centered on the sandal, adjust the buckle front to back to find a desirable location.
4. Now tighten the insole strap. This will dictate the buckle’s left to right position on your foot. Keep the buckle parallel with the bone behind your big toe. If the buckle is too close to the bone behind your big toe it may be uncomfortable. If this is the case, loosen the insole strap and reposition the buckle farther to the outside of the foot.
5. Now that the buckle is in it’s desired position and the insole strap is tightened, tighten the toe strap until snug and comfortable.
6. Tighten the heel strap to your desired comfort level and enjoy your Shamma Sandals!
Numa Lacing System
(Our Numa Lacing System includes Numa Warriors, Numa Chargers, Numa Maximus, and Numa Alphas).
1. First, loosen the two strap zones (heel strap section and elastic forefoot strap) until there is excess slack in each section. The straps should be extremely loose in both zones.
2. Start by centering your foot on the sandal, so that the placement of your foot is in the desired final location (you should have equal room in front of your toes and behind your heel with this placement).
3. Now that your foot is centered on the sandal, adjust the heel strap to fit comfortably.
4. Now tighten the elastic forefoot strap. This will dictate the buckle’s left to right position on your foot. The buckle will self-adjust so don't worry about placement. Push the elastic through the tension-lock buckle on the heel in order to adjust its tightness. For lifestyle use, you won't need it super tight, it should just be comfortably tight.
5. Make any adjustment on your heel strap if needed and enjoy your Shamma Sandals!
TrailStar Lacing System
(Our TrailStars Lacing System includes TrailStars Maximus, TrailStars Alpha, and TrailStars Omega).
Super Lacing System
(Our Super Lacing System includes Super Browns and Super Goats).
Models in our Super Collections have 3 adjustment zones for the perfect fit- the toe strap, the insole strap, and the heel strap.
1. First, loosen all 3 strap zones until there is excess slack in each section. The straps should be extremely loose in all three zones.
2. Start by centering your foot on the sandal, so that the placement of your foot is in the desired final location (you should have equal room in front of your toes and behind your heel with this placement).
3. Now that your foot is centered on the sandal, adjust the buckle front to back to find a desirable location.
4. Now tighten the insole strap. This will dictate the buckle’s left to right position on your foot. Keep the buckle parallel with the bone behind your big toe. If the buckle is too close to the bone behind your big toe it may be uncomfortable. If this is the case, loosen the insole strap and reposition the buckle farther to the outside of the foot.
5. Now that the buckle is in it’s desired position and the insole strap is tightened, pull any extra slack from the toe strap zone through the outside ankle slot towards the heel.
6. Tighten the heel strap to your desired comfort level and enjoy your Shamma Sandals!
Cruzer Lacing System
Our Cruzers models have 3 adjustment zones for the perfect fit - the toe strap, the insole strap, and the heel strap.
1. Adjust to Desired Fit
After centering your foot on the sandal, adjust the outside lacing so that the buckle is in a comfortable position and there is tension (but not too much) between the toe plug and ankle slot.
2. Pull On Power Sleeve
Adjust the heel strap by pulling up on the power sleeve, to create some space to tighten the heel strap. It should be enough space to grab the slack with two fingers.
3. Pull Slack Through
Pulling from the heel strap side, pull the extra slack through the bottom of the sandal until the Power Sleeve is resting in a snug position.
4. Pull On Power Sleeve
Pulling from the inside lacing side of the Power Sleeve, pull the extra slack through the Power Sleeve until the strap is flush with the sole of the sandal.
5. Adjust To Desired Fit
First, create slack underneath the buckle by creating some tension on the inside lacing side of the buckle. Adjust the lacing until comfortable.
6. Pull Slack Through
Take extra slack and feed it back through the buckle, towards the inside lacing of the sandal. Pull slack until the buckle is flush with the foot.
7. Put Extra in Keeper
To keep the extra slack secure, feed the strap through the keeper and pull until comfortable. You are now ready to explore!
