An apparatus removably attachable to a shoe with laces and a sole. The apparatus comprises a front side and back side, lower and upper opposite ends and opposite sides. The front side of the apparatus has a front pocket and the back side of the apparatus has a transversal strap extending between both opposite sides of the apparatus and a longitudinal strap extending from the lower opposite end of the apparatus. The longitudinal strap has an extendible loop configured to be removably latched onto a hook device located at the upper opposite end of the apparatus. When removably attaching the apparatus onto the shoe, the longitudinal strap is weaved through the laces of the shoe and the extendible loop is extended over the hook device so as to securely attach the apparatus onto the shoe.
