Quick answer 'no', off-road cleats are recessed into the shoe sole, road cleats stick out (and the shoe soles are stiff) hence the roadie duck waddle).Drake wrote:But are mtb cleats the same as the ones used on road machines?
Longer answer, if you want to walk any distance in comfort get off-road cleats and off-road shoes, which have more flexible soles, as well as recessed cleats. There's nowt stopping you using off-road cleats on-road: for example my favorite pedal on my 'bents is Shimano's single sided A520, if for no other reasons that it dangles at the right angle for quick engagement, and you don't want your feet falling off the pedals on a 'bent trike Road shoes / cleat systems are supposed to help you get more power to the pedal, due to their stiffness.
As for will cleats help off road, I'd say it depends. Some of my acquaintances prefer sticky shoes and spiky pedals, for some of the more technical trails. Personally I still prefer simple double sided clipless pedals (eg Shimano 520) for trail riding, just to help keep my feet on the pedals, but as I'm rubbish on anything technical I end up un-clipping if the riding gets tricky, in case it all goes pear shaped, (and sometimes clipping in again, by accident), so understand where the sticky sole brigade are coming from - no idea what the latter are like to walk in for any distance though.
