This is the fourth exactly-same-model of hiking boot I’ve worn over the last 10 or so years. A pair lasts two or three years — hundreds of trail and sidewalk miles. Then wears through, or the bottom sole begins to delaminate. Noticed today, as I purchased another pair, that the current pair is worn through on the heel’s outer side. So I roll my foot outward, or push outward, as I walk. The rubber nubby layer has been completely worn away and the basal layer below that is beginning to wear through. The previous pair was in tatters, with the soles almost flapping off, when replaced a couple of years ago.
Why am I bothering to write about this? Well, I’d like to encourage you to walk, or run, or whatever, until you also wear out your shoes. I put in about 10k (mostly in the city) every Saturday and the same on Sunday. It keeps me energetic. Clears the head. Musses up the hair. Makes me thirsty. Is actually relaxing. Feels really great.
