Great trainers, I usually wear a size 6 but ordered size 7 (I usually check the sizing first before buying) they fit perfectly, are very comfortable, look cool and provide just the right support and cushioning for my plantar-fasciitis ridden heels. I wore them for the Helvellyn Challenge in the lake district under extreme weather conditions. I saw many people slipping about in their trail running shoes but mine were simply perfect, even on wet grass, stones, mud and any other surface on the 10k run. I had no blisters, my feet are absolutely fine even though the shoes were only one week old, no problem with my heels either. If you haven't had a pair of Asics before, try them.
