Jellyfeet™ proudly offer three sizes for adults: 

Small, Medium, and Large.

For your conveniences, we have a size chart available below to help you select the right size for your feet. The sizes are based on your shoe size, so if you are a person that has size-11 shoes, you will want to order a size Large Jellyfeet™. This will be the most appropriate size as it will be easy to slip on and off without constricting your foot movements.

Jellyfeet™ are made from a material that is very flexible, so there are some people who could use either Medium or Large sized Jellyfeet™. Some people will prefer more tight fitting/compression for the activities while using Jellyfeet such as yoga, barefoot running, working out, or more. Others will find this uncomfortable, but no worry!

We offer a Size-Fit Guarantee.

If you do not like how your Jellyfeet™ fit on your feet, we will send you replacement of different size, no questions asked! The only thing we ask of you is to gift your pair that did not fit to a friend, family member, co-worker, construction worker, bartender, cab driver…. or anyone really!
