I skied them for a month straight bout 15-20times-was generous to them on rails and all over the mountain. Then the first spring skiing day came and the edges cracked,separated underfoot. Yes, they skied awesome....everything about the ski skiing is awesome, but I feel Dynastar has still not fixed the durablity problem with them. I ended up sending em back for warranty through my shop. Again, I loved the ski, but the durablity was poor.
