More ergonomic but skinnier? By 'more ergonomic' I'm picturing a Birkenstock forefoot shape. Did you mean something like that? However, by making the toecap narrower, wouldn't that be making the boot less ergonomic? I imagine that toecap width is something that gets determined by the foot the skates are built for. They should be the Goldilocks 'just right' width if scanning, building, and molding go as they should.
