I used these boots for cool and cold weather cycling. My feet get cold easily, so,they did a nice job of keeping them warm in 40 degree temperatures with regular cycling socks. I have not had a chance to use them below 40 degrees, and will west smart wool socks with them in 30 degree temperatures. I bought a size larger than I normally wear in order to be able to wear heavier socks with them.
I have never used a Boa closure, so I would have appreciated instructions with the boots on how to use this type of closure!
This boot works great for late Fall, Winter and early Spring riding. Keeps my feet nice and warm and dry without needing to resort to foot warmers. I've been out for two hours in the low 20s with no problem. Highly recommend!
I got it to replace my older Shimano MW7 boots. Compared to Shimano's, those run just a smidge small (I had to get next size up, however wish there was an in-between). Sole seems stiffer, breathability is good, but feet still get a little sweaty. With thick wool sock is good down to freezing, with toe warmers maybe good to low to mid 20s. Unfortunately (fortunately?) have not had the chance to test them in the rain.
