La Sportiva Skwama Rock Climbing Shoes are pre-owned shoes. I wore them for one session in the gym and realized my foot was too narrow. Rubber is 98% - see photos. The shoes come in black and yellow colors with a yellow main color. The shoes are made by La Sportiva and are of size 10.5 (US) or 43.5 (EU). Great bouldering and sport climbing shoes with the vibram XS grip 2 rubber.
