There are some folks out there who believe that a shoe is a shoe. Au contraire. Here's the deal — the biomechanics of every foot is different, as is every style of running. Some runners have a gait that tends toward pronation and others roll outward (also called supination). Choosing the wrong type of shoe can not only hinder performance, it can also lead to injury. This is why SportsShoes.com has a team dedicated to finding the right shoe for every runner. Shoppers can send a video of themselves running (or do the wet sock test) and their experts will analyze it and find the perfect style and fit from their massive inventory of top-brand shoes. It's no wonder they're the number one running retailer in the UK.
