I've been wearing Kinvaras for faster paced distance runs, tempo runs, fartleks, etc. and I like them a lot but I need just a little more stability. I've been looking around and I'm leaning towards the Mizuno Musha. My local running store doesn't have them though, so I'm wondering if anyone could tell me how they feel as far as fit and cushioning are concerned. Like I said earlier, I'll be wearing them for quicker stuff, probably 3 times a week and up to 9 or 10 miles. I know that the Mirages are sort of the "stability version" of the Kinvara, but I want something a little close to a flat. Any help is appreciated.
