A shoe feature is composed of four parts: the TREAD, VAMP, WELT, and insole. The TREAD is the bottom of the shoe, which provides traction and grip on different surfaces. The VAMP is the upper part of the shoe that covers the toes and instep. The WELT is a strip of leather or other material that runs around the perimeter of the shoe and connects the upper to the sole. The insole is the inner lining of the shoe that provides cushioning and support for the foot.
