I keep walking holes into my boots! Am I doing something wrong? Since February I've been taking the dog out everyday for an hour or two across the relatively gentle hills of the Pennines. In that time I've gone through four pairs of boots; from dirt cheap Karrimor to Jack Pykes. In every pair, the soles get worn into oblivion despite not having a pack, not running in them, not crossing particularly rough ground, and so on. I'm not fat, gigantically muscled or 7 feet tall... could it be my walking technique or lack thereof? Would it be better to buy a completely different shoe?
