I wore my Lake shoes with chemical toe warmers- which made them a tiny bit tight, but I guess the extra heat made up for it. I considered the platforms, but I don't have clips and straps big enough to get around my boots and I couldn't imagine mountain biking without being strapped in somehow. It was actually pretty warm in there once warmed up- I ended up opening up my jacket and switching to thinner gloves after 30mins or so.
