Numa Chargers

Numa Chargers are designed to give you the ultimate barefoot experience on the toughest city streets. Numa Chargers are simple to use, a breeze to put on and they seamlessly connect you to a sole that is perfectly tuned for life in the city. You’ll never look at concrete and asphalt the same way again.


Chargers use a 6mm Vibram® Morflex sole coupled with your choice of our UltraGrip or Tobacco Brown Goatskin Leather footbed. Chargers have a 7mm total stack height. A blend of rubber and EVA, the Morflex compound is known for being lightweight, with a firm but cushioned feel underfoot. Morflex is also known for a quick break-in time. While not as thin as the Warriors, Chargers are a better choice for people who want to go very thin but would like a small amount of cushioning. Pair with the UltraGrip footbed for use in the harshest elements, or select the Goatskin Leather for more comfort in drier conditions.

Numa Lacing System

Numa uses a handsfree slip-on lacing system that stretches with your feet as they move. The result is our most comfortable, seamless, and easy-to-use lacing system yet. The secret is our custom ¾” elastic forefoot section. This innovation gives the lacing system the ability to stretch where you need it most: over the arch and middle of the foot, creating a seamless connection between your foot and the sandal. Added benefits of this system include a self-adjusting toe plug buckle and forefoot strap that is custom-cut. This allows all our Numa Sandals to rival flip-flops in terms of comfort without sacrificing convenience. This system uses our innovative and flexible heel posts to keep the heel strap in an optimal position, and these laces are made using Ultrasuede for the highest level of comfort available. Comfort, connection, and convenience are waiting for you with the Numa lacing system!


Just because you wore a hole in your sandals, it doesn’t mean you have to throw them away! Our modular approach to sandal-making means that worn out parts can be replaced with a pair of pliers at home. Why throw away what you can repair? Visit our Parts Page to learn more!

Made in the USA!

Proud to be made in the USA and we wouldn’t have it any other way! All of our sandals are made right here in Santa Cruz, CA by our small team. Follow us on Instagram and Youtube to get a glimpse of how we do it on a regular basis.

Great design, too loose on low volume feet

Great design on the elastic laces, but with low volume feet I had to do them up tightly which became uncomfortable. Perhaps cotton over the elastic would be good, whether that's an option. I got the charger soles which I didn't like as they don't have the grip I needed, I know Shamma has come out with a Numa Maximus which I think would be better as the soles are more rugged and with better grip.

Happy with my numas

they are now my go to sandals - somehow the elastic on the top keeps them on my feet very comfortably. the ultra grip footbed is also very cool.

Best Sandals on the Market!

After trying literally every brand of "running sandal" on the commercial market, I can tell you from solid, barefoot / minimalist ultra running experience that Shamma has got it locked in! Their design is comfortable, capable, and without compromise. I'm running in their Warrior's, and will never go back to any other manufacturer.

Numa Sandals and Customer Support

Love the sandals. Customer support is awesome! I was excited when my order arrived. Couldn't wait to try them before my upcoming trip to Central America. My wife's fit great and she loves them. I was disappointed that mine seemed a little too small though. I contacted customer support and worked with Catie to get the issue resolved. Catie worked with me to figure out what happened and get them fitted correctly. Turns out my feet are different sizes (probably why my feet hurt in some of my other shoes). Return for correct fitting sandals was seamless and flawless. I highly recommend watching the measurements video and sending them pictures to get the best fitting sizes since they're custom made. Now they fit perfect and I love them. I'm already thinking about getting another pair in leather this time.

Yes, I will buy again

Everything and everyone at Shamma have been great. I now have 5 pairs of different versions for different uses. And I am looking forward to my new boots when they get them finished. Obviously I am very satisfied and replacing my "drop" shoes. It's getting a bit chilly for sandals in the winter here, but come spring I plan on trying out some new styles. Thanks Shamma for your commitment to quality in a small company. You folks are a great team.
