My current running shoes (Asics Gel Kayano 17s) are inching up toward the 300-mile mark. I also occasionally rotate in my previous 17s (inching up toward 500 miles) for short runs, because they don’t feel thrashed yet, although I wouldn’t wear them for more than a 4-miler. They don’t make this model any more (pour one out) and I’ve stockpiled 1 pair of those, and 1 pair of the GT-2160s (same year, slightly less padding).
If I have 2 brand-new pairs of shoes with which to start marathon training, plus my current kicks, am I covered? There are still a few pairs of 17s out there at discount, but the stock is getting few and far between. I could switch up to the 18s but would rather do that sooner, rather than late in marathon training. Should I buy more shoes?
