These shoes are just the right amount of aggressive and they stick very very well. I was able to climb a 5.11 with no slipping issues on the smallest of holds. All of my shoes are So Ill brand and they keep me coming back! I found the sizing suggestion on the website to be very accurate. They are difficult to get on at first but after one or two climbs they are very comfortable.
These are the absolute best shoes I've worn since I started climbing 4 years ago.
I started with the standard New Zero and loved them, so I decided to give the Pro a try and it was so worth it. The softness of the shoe takes no time at all to break in. I have tons of confidence even on the worst feet because these things smear so well. The upper is super soft and comfortable, but the extra rubber makes them feel very sturdy and secure. I throw these on for anything with even the slightest overhang and even some smeary slabs. Like I said, you can't go wrong with the New Zero, but these were definitely worth investing a little more.
