I got the Vasque Catalyst approach shoe recently. I just came back from a climb of a nice rocky mountain today and they were great. They have the same stickiness as five tennies, but the seams are constructed better. I had no sore spots at all.

While those three adjectives almost sum up the Catalyst experience, other words inevitably come to mind: comfortable, high quality, well balanced, and roomy, just to name a few. As an “approach shoe,” these are more of a trail runner with a sticky Stealth rubber sole than a day hiker, meaning they favor flexibility and grip over ankle support and ruggedness. The forefoot offers adequate cushioning without sacrificing feel, and a broad, stable center keep you balanced. The spacious toe box seems almost too generous, although the solid lacing system keeps your foot snugly in place. If you run small in your size (as I do in a 12), you may want to consider buying a half-size smaller. All in all, superb for scrambling and hiking in warmer temps.

I was looking for a pair of light-weight hiking shoes to use in tandem with my Vasque Clarions and these shoes fit the bill perfectly. After replacing the standard insoles with Superfeet insoles, I have logged around 30 miles on the new Catalyst's and they are great! No blisters, no pain, and they stick to slippery rocks like glue. Make sure you are a little more cautious about twisting your ankle (versus traditional boots), and you will enjoy these shoes for many, many miles.

Great on rock, garbage on ice. These things are extremely comfy. I wear them on a daily basis as my kick around shoes. The sticky rubber provides great traction PROVIDED that what you're walking on isn't cold. When cold, the rubber's traction is rubbish. Don't even try these things on ice. That being said, everywhere else they're fantastic. They fit my high arches decently, and give nice cradling. The insoles and tread are pretty ordinary, nothing amazing but nothing terrible either.
To summarize - These are killer in canyon country or as bum around shoes, not so hot for winter usage.
