Subject: Boston Marathon: Old Shoes / New Shoes? So . . . I messed up a bit with the timing of buying trainers again, but this time its thirteen days before the Boston marathon. My Brooks Glycerin 5's have 450 miles on them, but the midsole doesn't seem to have compressed and I haven't felt like they're providing less cushioning, . . . until today. While I'm still comfortable running in them, I'm worried about what may happen if I hit 500 miles in them on Heartbreak Hill. I know that shoe-wear is not a science, and that wear and loss of cushioning is gradual. I'm a fairly balanced runner, don't scuff my feet all that much, and have a low stride, so I don't pound. I've heard that shoes can wear out anywhere from 350 - 700 miles, and I usually run in mine for about 500. I've got 13 days until Boston -- possibly time enough to break in a pair of racers. Advice? |
