I'm not a long distance runner. I run 5K 2-3/week max. Normally I wear one pair every other day and another on the off days.
so my shoes last a bit longer than normal 6 month swap out.
I use these on treadmill, elliptical, street, bike and just walking the dog (saturday is 5k dog walk when its nice).

Average arch, weight and speed - these shoes work great. but to be honest so are the 2170 or are they now 2270s?

When I can get them on sale for a price like this I stock up on a pair. this was less than half they would have cost me, even at military exchange store.

Just bought newest - going out of style version stocking up for summer.
