I've had mine since April, and I've used them (along with a heavier, better cushioned pair of shoes for easier/longer sessions) for racing and hard road sessions.
Have been racing quite a lot recently on the roads (3 10Ks & 1 5K in the last month plus some q long hard sessions), and my knees are starting to feel like they've had a good pounding.
Does anyone else have any experience with these and how long I can expect to keep using them? I suspect I've probably done about 200-250 miles in them thus far.
