The Black Power Straps have been great on the gravel trails. No fear of the sandals moving from under foot. I am able to keep eyes on the coming trail confident that my Cruzers or Maximus will go where my feet go.
My overall experience has been great. I wanted the red Cruizer but with a Warrior sole and Shamma delivered. I also purchased power straps. I have struggled with the lacing system, but I am working on it. I actually find I can't use the power straps because they pull my foot off the shoe. I will probably go back to the Warrior, but I do love my bright red Cruiser.
Thank you!

These are the best fitting and most comfortable Sandals ever. The thinnest ones are the best… two issues though- the leather dye comes off on my feet which makes me feel sketched out.
Second is the synthetic black fabric of the sandal makes my feet itch right where it touches my skin. I wish they had a 100% natural material, and selected leathers that have no dyes. Would be cool to have grounding thread but can’t have it all!
My feet are secure in the Cruzers. They significantly reduced the shifting of my smaller right foot in the sandal. I don't like that the velcro catches on the webbing and abrades it. Overall, I couldn't wear the sandals without the power straps so I'm glad I bought them.

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!
