Building on AMS’ shoe fetish, I personally use HeroMachine a lot for modern settings and would love to see some new athletic shoes at some point. There are a couple in HM 2.5 and here are a few references. Sadly I don’t have a contest win to fall back on but does dire need count?

Just a thought to give us more variety with modern characters.
