The M225 is Shimano’s top of the line shoe with a carbon sole, ratchet adjustment and spikes in the toe.
I have to say these are really nice shoes. I have used these through a season of cross, plenty of mtn biking and daily commuting and they still look new. The ratchet adjustment system holds them on tight. The spikes will tear your shoe covers apart, so keep that in mind.
I usually wear a 44, or a 10.5 in us size, and in these a 43 fits perfect. Get em’ you won’t regret it.
