Abstract
A lightweight bouncing sandal for youths, comprising a tough thin bottom layer, which is durable enough to withstand repeated scuffing and impacting with the ground and has an exposed textured surface to provide traction and reduced slipping when wet, a middle resilient layer of sufficient size and thickness to support a seventy-five pound load without compressing fully, a top confronting layer of semi-flexible material, with sufficient thickness and rigidity to support a two and one half pound per square inch load without distorting, with at least one elastic strap permanently affixed at its ends, such that it lays flat against the top layer without slack in a relaxed state, with an asymmetrically curved base to aid the user in maintaining balance while running, jumping or walking.
