Some recent experiences:<br>
- Asics GT 2100 - 550 miles<br>
- NB 766 - 560 miles, still felt great, but retired them anyway<br>
- Brooks Adrenaline 6 - 490, but should have retired at 425, ended up with foot injury<br>
- Asics Gel Kayano 12 - 425, still going, but will probably retire these at around 460<br>
- Brooks Trance 7 - 105, no signs of deterioration at this point<br><br>
I am very heavy (230), but do not punish shoes, all of these heels have held up great, forefoot cushioning is the deciding factor on retirement. I rotate at least 2 pairs, this seems to lengthen their mileage.
