I felt like I could boulder for longer than before, which means an improvement in endurance. The skin started to feel a bit sore after about an hour. I still have trouble with the blue boulders (up to 6B) since they require strong hands. I tried the circuit and I could barely do a 6A+, but I was happy I could stay on the wall when I was tired and was ready to give up. My hands stayed gripping tightly on the handholds. The foot placement could definitely improve.
I tried on my Tarantulace after they have been resoled with "unnamed rubber". The rubbers are pretty sticky and I have no problem with the resole job. I could however really feel that the shoes don't squeeze the toes together enough. They are sufficient for boulders at my level, but I could see that I won't be able to reliably pushing off of them hard enough for harder routes. The resoled ScarpaVapors though feel reeeeally tight. I'm hoping that the rubbers would soften up a tiny bit after several uses. I'm still hoping to find a pair of shoes that cause less pain to my feet than the ones that I own.
Things to work on: core strength, grip strength, endurance, foot placement, reading routes, hip placement, balance.
I'm also hoping my feet would strengthen enough for them to hurt less in climbing shoes in general.
