I know that Emerica is quite the lightning rod on this message board, but if you like them, they're selling three different colorways of the non-G6 Gamma on their website for $20, with free shipping.
If I wasn't drowning in shoes, I'd buy a second pair of the all black ones. They skate well, and pass my all-day comfort test. I wore a pair of these at work for several months, and they held up really well (I do a LOT of walking at work because our department spread across an entire building floor, and has other areas on two different floors, shit's lovely). I also saw Rammstein in a pair of these shoes from the GA Floor section (non fire-zone), and I wasn't in crippling pain after standing in these for about five hours. So, $20 is a steal.
