Track and field — a snug fit protects. Shoes for serious track and field athletes should fit like a glove. Since the heels of these athlete’s shoes are firm, providing ample support for all of the athletes’ repetitive movements, a snug fit is a must.
Soccer — shoes should fit like a glove. Because soccer players are mostly upright, yet have to perform zigzag movements as they move the ball around with their feet, they need shoes that fit like a glove. The heel area is not well-padded and firm, so to avoid blisters, a snug fit around the heel is another must.
