I use these with my Crank Brothers Candy 2 pedals. They're absolutely wonderful and fit great provided you have the right size (I did have to make an exchange after ordering too big when trying to heed people's warnings - I went too far over).

So, bearing you have the correct size, they tighten easily with the velco straps. I wouldn't want to take a long walk in them, but they're serviceable for getting around when you're off the bike. I've been using them for about a year now, and I'm hard pressed to find a fault in them.
