Boots were uncomfortable due to being a 1/2 size too small even though I ordered a 1/2 size larger than normal. The speed zone lacing is awesome! The liner has built in cushions to lock your ankle in the heel and this caused some minor bruising on my calf the first few days, but it broke in after a bit. Taking the liner out and flexing it and the boot on the natural hinge of my foot seemed to help with the comfort. Felt lots of control on the board. Dogfunk is sending a replacement so hopefully the correct size will make the difference.
