Road - Speedplay X on Carnac & Northwave road shoes
Mtb - Speedplay Frogs on Northwave mtb shoes

A comment on shoes: I found, too late, that my feet did not fit the tapered-down toebox of the Sidis I first used, even though I bought them slightly large. After several thousand miles in them I ended up several times with bruised nailbeds on my big toes - ow! I switched to Carnac and Northwave (only at clearance sale prices) because the toe area on those brands is more bumped-up and boxy than on the Sidis. So from one who learned the hard way, it's a good idea to take into account any quirks your own feet might have
