Everyone has different preferrences, but I've been touring in a pair of these that allow me to use spd cleats, but still walk comfortably when off the bike. Sizing does seem to run on the small side. http://shop.pearlizumi.com/product.php?mode=view&pc_id=43&product_id=2328453&outlet=&color_code=021
Thanks! Interestingly, those are one of the pairs I ended up getting. I like them, though they are around a half-size too small. I tried the next size up, but they were a bit loose, so I'll see if I can suffer through the ride with them; hopefully they'll stretch out a bit.
