Yep - give it a few days of testing/learning - but yeah, it does massively effect pedal efficiency once you get the gist of pedalling full circle - you may expect to fallover at 0mph because you can't lift your foot off the pedal as you're used to... but if you're used to clips/straps, I would guess the idea is the same.

I'm likely in for Friday, and depending on the daughter situation perhaps Saturday and Sunday too (assuming I get enough rest ).
