I had the 236. I did not like them. They fit well, but they were very heavy. The materials were thick, meaning they were quite warm. Also, the BOA system was a disaster. On the 236, the dial was behind the heal. I think that gave it too much slack in the cable. Basically, when I would pull up, the BOA would tighten across my toes while my heel would slide out of the shoe.

I know with the 237 the dial is moved to a more traditional location. I am not sure if that fixed the problem I experienced.
