I'm 50 and have only been climbing for 5-6 months; mainly in a gym. However, I do climb a lot and these RAs are my second pair of shoes. All I do is boulder and can climb up to a V2/3 inside.Pros: Comfortable, well designed, just aggressive enough for me, no stink, quality, unique, little stretch, comfortable tongue.Cons: For me the low volume heel is somewhat of an issue. At the right angle, my heel can slip, so that puts a bit of hesitation in my mind sometimes, but that is the only con for me. Your milage my vary.Sizing: I wear an 8.5 street shoe, I could have worn these in a 7 except that I broke my left big tow when I was younger and have trouble bending it, I chose a 7.5 which is a hair big on my right, and still somewhat uncomfortable on my left, but they are stretching just a bit and getting more comfortable on the left foot.Similar to a Supermocc maybe, but the 5.10 heel fit me a bit better. However, I like them very much.
I have been climbing in the Tenaya Ras since September 2012. I used them to work a Rifle Colorado route, "Eurotrash." The route has a thin technical crux down low and a steep crux up high with a heel hook. The Tenayas performed great on the small polished smears and tiny divot on the first crux and heel hooked nicely on the steeper 2nd. I like that the heel stays snug without chafing without too much room in the heel box. They are a great all terrain, high performance, comfortable shoe.
For the first time in years, I can take only one pair of shoes to the crag. They perform as well as any shoe I've worn (used to be a Miura-lover), and they are hands down the most comfortable shoe I've ever worn. Somehow they pull that off without any slop. The XS is the gold standard in rubber, and i LOVE it. It lasts really well, and is so sticky you can toe-in on SLOPERS. After using this shoe for a year on everything from Hueco Tanks boulders to big alpine routes, I can say its the most confidence inspiring and well-built shoe I've worn in my 12 years of climbing.
