Artimust,
The Storm (high end) are elevated higher off the ground than the 3G's so I've found myself to typically stop quicker (using comparable soles). The Storm molds are the same as Dexter (not sure from which Dexter models) but the difference for me after comparing to my SST8's, the 8's are broader across the front part of the foot, making them feel more "clunky".
In short I'd say the 3G's and Storm shoes share about the same widths but differ greatly in elevation and material texture,
3G's being ultra soft and SST8's rigid
