I now have the chance to buy a US 10 of the Volt Mercs.
Will these be way too big?
I have Volts 1 size up from my usual size (not by choice, just bad seller description). It is not unwearable. It's not as snug as TTS and you don't feel the flywire as tight (which can be a good thing), but obviously there is at least an 1 inch of room in the toe. If you want to wear them casual and not do anything too strenuous in them, I think 1 size up from your mercurial size would be okay. You can tighten the laces decently tight so your foot won't be sliding too much. Not ideal, but wearable.
