Nails should be trimmed straight across and kept short. Walking barefoot should generally be avoided to prevent cuts, punctures, foreign bodies, insect bites and certain parasitic infections. In my experience with travellers, the majority of foot problems are caused by poorly fitting or inappropriate footwear. I've come across include frostbite caused by hiking in snow wearing running shoes, a sprained ankle from climbing in sandals and, of course, blisters. Socks are also a factor, and should be chosen to suit the activity.
Friction blisters are probably the most common foot ailment in active travellers.
Although blisters start out as a small irritant, they can become serious enough to literally stop you on your feet. Excessive friction or rubbing, moisture, lubricants, the weight of a carried load and intense or long periods of activity are the most common causes. The best way to avoid blisters is to wear properly fitting shoes and to break them in before embarking on a long or intense journey. Socks or liners should fit well, with no bunching, and be able to wick sweat away from the skin. Visit our foot Aliments, Prevention and Treatment Guide .
