Best shoe I have owned. Heel is a little soft for some hooks, but allows for a larger contact area. I wear a 42 in the solutions, and a 41.5 in the test. I use them for Bouldering and short single pitch routes. No complaints so far. They've sent V5 and 5.10c with no problems.
I just ordered 30 of these to replace most of the biners on my rack. I am hoping for the smaller size to cut down on bulk. I have done quite a bit of research and found nothing that suggest a smaller biner is a bad idea. Anyone have any other thoughts on using these biners for multi-pitch routes?
