Unsafe at any distance
"Terrible compared to older models. One, the heel strap is too short so that the velcro does not fully engage. There's only about a one inch overlap instead of 2. 5". Two, several of the seams are on the inside causing chafing and blisters. My little toe and top of my left foot have yet to recover. Considering the price, I'd suggest getting a cheaper imitation."
