Tbh I'm not sure if it's shoes or if I need better running socks, but my second smallest toe, and to lesser extent the middle one get rubbed just above the toenail when I run. It doesn't quite cause a blister, but it kind of forms a very thick skin, that you can peel off.
I was wondering if anyone else had a similar issue, and if there's a certain type of trainers I should be looking for? I am wearing a size bigger than I normally do, and I have narrowish feet.
