OK, all you experienced walkers/hikers, I'd be grateful for some advice. I'm off on a wildlife watching holiday on Vancouver Island Sept. 2015. I have bought some lightweight, waterproof walking boots, which fit well and are very comfortable on the foot, but I'm worried they may rub around my ankles, where they feel a little stiff and uncomfortable. Will this stiffness ease if I wear them in? Would blister prevention socks help?
