I have about 20 days on my SPK boots and they still fit great. The break in is not as much as you would think on a boot like this. I thought it was going to be sloppy after like 10 days but it is not. It has a great hold on the foot and it is the most comfortable boot for riding switch in. Not to mention the boots ski the whole mountain very well. I was on a piar of Prophet 90's and the stability with the SPK boot and Z12 Ti Binding was one of the best setups I have been on for a while.
