Here we have a new pair of support running shoes I've been advised will help with pain I've been getting in my left foot/ankle during and shortly after a run (typically 10K) I've been told by a retailer that I Pronate when I run. I'd never heard of this before. So I'll be giving these a whirl and see if they solve the problem :)
