I've been thrilled with my new Keene Growler insulated hiking boots worn up several mountains on snowshoes, warm even when around 5 degrees, lightweight, and no issues until now. Ordered a full size larger to acommodate wide feet and thicker merino wool socks with liner. Perfect fit-not loose or tight. But now after 5 day full days (spred out over a month) of comfortable wear, there are sore hot spots felt on the outer smallest toes, worse on one foot than the other. Only felt when these boots are put on, not with all shoes. No blisters-just painful areas when the boots go on. A quick remedy is moleskin or equivalent but puzzling why issues have arisen after break-in. Suggestions?
