well i run on a rubber track with them,
also, i dont seem to have any luck with finding powercats in stores or online in my sz 9 for a low price, so i prolly mite have to consider the superfly r2 from the runningwarehouse as a last resort, lots of ppl wear them at track meets, so does it fit true/big or should i go 1/2 size down if i were to use them barefoot.
