I have to weigh-in on this shoe. First, let me say two things: One: I love the Mad Rock "Flash" and will soon be buying a third pair. Two: I bought the new Mugen on-sale at EMS for $50 over a year ago. Don't like it! Whereas the first Flash's I wore impressed me with their sensitivity--and, in short order, with their comfort--the new Mugen is "clumsy" and rather uncomfortable--resisting break-in, thanks to it's lining. (By contrast, wear a properly fitted pair of un-lined Flashes for one outing and they will mold themselves to your feet.) The dual-density sole has "fuzzed" on the inside edge making for somewhat-decreased edging precision over time. Also, the heel-cup is more shallow than the Flash, giving a less-secure feel when heel-hooking. Trust me--there are reasons why you rarely see the "clown-shoe"-cosmetics of these shoes on the pro's in the climbing mags--or at your local crag.

Plenty good shoe! I've used them bouldering, sport, and trad--fine all-around shoe. You can fit them tight--the unlined upper will give nicely the first time you wear them long enough to heat them up on your feet. Edge and smear well. Comfortable enough for long trad routes. Precise enough for bouldering. Easy on and off. And you can't beat the price! All the shoes I've previously owned were over $100 a pair. So I wondered how the Flash would be. Now that I've owned and used them--who needs resoles?!
