Got a pair of these as my second pair of rock shoes... and I LOVE them. The smallest footholds feel like massive ledges, allowing me to comfortably put my entire weight on them. I have seen a massive improvement in my climbing since I've gotten these.
The only thing that bugs me about them is the velcro straps are a bit long (especially given my small foot volume), but they never really get hung up on anything, even when I'm matching my feet, so it's really only a slight annoyance.
That said, the circular velcro sections that the straps adhere to are super nice, allowing me to apply the tension of the strap exactly where I want it for the best fit.
As with any climbing shoe, I would highly recommend trying on a bunch of different sizes of the same model before pulling the trigger, especially with these given they aren't the cheapest kicks.
