You use what ever boot binding interface you choose. I use straps and soft boots. Your bindings or mounting to plates that slide over pucks, which are set to your stance. So you can go hard boot, soft boot, straps, step ins, plates, whatever you like. The plates slide off the pucks and quickly move to tour mode. Then you just tour in your bindings. It's a pretty simple setup, but for some pics chick out Voile's
site. I have toured several miles over three years on my original setup. After about 140 days I broke a tail clip. After 180 days I cracked my slider plates. None of these problems caused me to lose a day of riding. Very, very reliable.
