Size Matters
When it comes to the part of you that supports your body we do not take any chances. Not on fit, not on performance, and definitely not on style. Biion’s are made up of EVA - a flexible, precision fit material. Take your play time with extra play, the more you wear them the better they feel.
Full sizes only. If you typically wear a half size we highly recommend going down to the next full size.
