Have a gift certificate to get some Kswiss shoes -- I've tried the Big Shots in store as well as the Approach IIs, and of the two I like the Approach IIs more; more cushioned, more form fitting around my foot. Anyway... Also intrigued by the Speedster (as I like light shoes for tennis), though, and wondering if any users of either of these shoes have any comments. I can't find any Speedsters to try on locally, so if I went with them I'd be ordering so any comments appreciated. Also wondering: someone on another site said something about the Approach II insole not being removable -- is this true? I like the option of putting my Superfeet Blue insoles into the shoe, so this worries me but I didn't think to check when I tried them on.
