I tried these on in size 6.5 3 separate times before making the purchase. They were prefect in the store - extremely comfortable to walk in (on flat ground), lightweight and warm. However, it was a different story on the slopes. My toes were suffering from excruciating pain. I contacted K2 and was advised to loosen the boots, which I did to the point of getting much heel lift, but the sharp agonizing pain never went away. I decided quit these and went back to my Burton Lodi's in 6. I have yet to feel that unbearable pain. I contact K2 again and all they said was sorry. I would not recommend these or K2 to anyone.
