Yes every gel and fabric product in this collection is designed to fit discreetly inside most standard everyday footwear without significantly altering the fit. The Gel Toe Sleeves, Fabric Toe Sleeves, Toe Crests and Toe Separators are all slim and low-profile enough to sit comfortably between the toes and inside the shoe without crowding the toe box. In very narrow or pointed toe box shoes there may be limited space but in most standard footwear these products fit comfortably and work effectively without requiring any change to the shoe itself.
