If I have a very wide foot, does that change my size?

If you have a very wide foot and are on the top end of the size range listed, you may choose to go up a size in the Alpha Shock. For example, if you are a size 7.5 with a wide foot, you may be more comfortable in a size Large Alpha Shock instead of the size Medium. Your sizing in the Infinite or Performance Shocks should not be affected.
