After 2 hours they were rendered useless...
When I first put them on was happy with the fit, compression and warmth.  After 2 hours of battling them sliding down the ribs that are built in (I think to hold them up) bent and now actively pull them down.  This is a serious design flaw for knee sleeves that cost this much!  They simply won't stay in place as well as a pair I have from MAVA with no ribs to bend and a grippy band to keep them in place.
