Apolla Shocks are sized by grouped street shoe sizes. If you have wide feet we suggest to order one size larger. The socks should fit tightly and secure on your foot without sagging. A snug fit is recommended.
Product sizing is to be used as a guide as the actual fit may vary. If you have any concerns about product sizing please contact us prior to ordering.
