I used these gaiters on a three day pack trip to Kings Peak in May 06. Three days of heavy, wet snowshoeing and hiking. They attached flawlessly to my MT Boots. The under securing leather straps had some stitching that frayed a bit on both gaiters. They were a bit short for over calf gaiters. They secured firmly on my calf muscle which started to ache after several hours. I am 5'8" having average size legs. They could be a bit higher, so they ride well above the calf, just under the knee. Because of this they continued to fall down. I had to pull them up time after time. They did not allow any snow or water to penetrate. They did not breathe well and became very moist. They stood up to numerous rock poundings and did not let any snow in where they contoured my boots. Overall, very rugged and tuff. I will keep them for scrambling and low wet conditions, ice etc. I would not recommend for multiple feet snow excursions.
