Ah, that's cool, in that case you probably don't even need new shoes - the Chrome shoes are basically the same skateboard style shoes. Just pedals with pins would work.

You should not have any problems with your feet not sticking, but if you did, like I said the Five Ten bike shoes are flat soled but use a special rubber compound that is incredibly sticky on pedals with pins as well. And like I said, I actually found them a little to sticky, would have had to remove some of the pins for it to work for me. Just an fyi if for anyone reason you don't find the new pedals sticky enough. It seriously felt exactly like clipless, unless you unweighted the foot and pulled it up off the pedal. It really grabbed onto the pedal.

It's my opinion, but I think both clipless and flats have merits to them. No doubt clipless is the best way to keep your foot attached to the pedal when spinning at super high cadence. Flats are easier to hop on and off the bike with. Efficiency like I said is a matter of debate, with some studies showing no improvement with clipless and others showing a small improvement. There's no clear answer at this time.

I think straps suck personally, it's the worst of both worlds - no efficiency gains, not better at retention than clipless, and also harder to get out of in an emergency. I really think a pedal with pins would solve your foot retention problem (keeping your foot on the pedal), if it doesn't Five Ten shoes 100% certain would. And no more straps making it take longer to get a foot down.

Good luck with whatever you choose. :-)
