I've ridden with the Shimano MT-38's for two years, and they have started to rot apart from wearing every day in all kinds of weather.
Shimano has replaced these with the MT-40, which fits perfectly and works exactly the same as the MT-38's.
Of note, the MT-40 has a velcro strap that covers the laces and keeps them out of the chain.
Additionally, I think laces offer a better fit, but they wear out about every six months.
I carry an extra set of five hole laces just in case.
I think Performance has these shoes for $50 or $60 right now.
I find them very comfortable for walking, and my cleats never hit the floor.
