Looking at a set of these: http://www.wiggle.co.uk/dhb-m20c-carbon-mountain-bike-cycling-shoe/ for long pedally rides, has anyone used them? How did you get on with them?

How does the sizing compare to Shimano sizing?

The cheaper DHB shoes get rave reviews anything I should know about the slightly more expensive versions?

I have them.
They were my first pair of SPDs though. Use them both on the mountain bike and road bike.

They seem fine to me. The rubber grip at the back of the sole is wearing away a bit. They take a while to dry out if they get totally sodden (winter MTB-ing).

I’ve started getting hot spots on one foot, though only after about 18 months of use? Tried moving the cleats around a bit but haven’t really figured it out yet.

Dunno what Shimano sizing is, I just bought ones the same size as my trainers.
