Size Advice

Running shoe sizing is very personal but we would recommend that you have sufficient width that you can wiggle your feet and enough space at the front. We typically recommend around half a thumbs width to give you sufficient space. This usually results in you going up half a size from your regular shoe size. These elements are all key to avoid you suffering from blisters, rubbing, pins and needles and black toenails.
