I used to be addicted to these..
But they wear out too fast. I climb cracks about three days a week. I've gone through four pairs in a year and I always blow through the resole period before two months. I developed a neuroma on my second toe because the shoes wore through in three months and the cracks were rubbing against my skin. It would be nice if the rubber covered a little bit more of the toe/side. They stretch about 1.5-2 sizes for me, so I downsize pretty heavily. I would only downsize 1-1.5 for cracks. These shoes aren't the best for edging, especially when they're the slightest bit loose, so on multipitch I prefer TC Pros. I use these for a gym shoe and single pitch trad.
