When I climb up hill or walking level I have no problems. But when I go down hill my big toes hurt and depending how far I go I can feel it for days. Last weekend I went 4 miles down hill with only a 15# pack and four days later I can still feel the tingle. I train with a 45# pack at least 3 days a week going down hill .8 miles. My boots are Lowa’s made for carrying weight and they are a half size larger then my street shoes. Going down hill my toes do not touch my boots. I have tried to tie my boots so I don’t have pressure over the arches but nothing has helped. My age is 60.
