Whatever shoes you get, don't get nike shox.
There heavy.
Or they cost way too much just to put them through hell with endurance running.
For some reason, I can't find much on the Nike air coos i got over the summer.
I got them for about $75 right before cross country season started, they felt like a dream and lasted the whole season.
speed workouts, endurance workouts, trails, roads, everything.
They were beasts.
And pretty light too.
Highly recommended.
