There are a couple of instances where I think the Speedplays could be problematic, though. We don't have a paved driveway, so there's no easy way to come and go without walking through a mix of sand/dirt/grass for a short distance on a regular basis. I also do at least 1 race/year with a grass transition area and a few yards of running on asphalt before we can mount and after we dismount. Looking at the Speedplay cleats makes me assume that these scenarios could really cause some headaches, since the mechanical bits are on the shoe, rather than on the pedal.
