My first time in these shoes was in Yosemite and they were very unnerving while breaking them in. In the meantime, I wouldn't lead with them. After a few multi-pitch routes, some gym climbing, and best of all...some steep slab on Glacier Point Apron, which really boosted my confidence in them. I have now come to love these shoes.
Most obvious is that they are edging machines! I have never been able to edge so well. My first climbing shoes were the Mythos, then the 5.10 Grandstones, and now these. They are relatively way more comfortable when stuffing into cracks...even finger cracks.
I LOVE these shoes now. I no longer wear my 5.10 Grandstones and am selling them now. I don't think I'll ever wear anything other than the TC Pros!
