Only worn inside at the gym. These are pretty true to size. They still have a lot of wear in them. I'm only selling because my feet are spreading out and it's time to size up. These are barefoot style shoes designed for lateral movement. "With rope-gripping rubber inlays and a high-traction sole, the all-new 360º is a lightweight cross-training shoe designed to handle court sports, parkour, CrossFit, and just about anything else that requires quick lateral movement."
