Got a pair and on the whole very pleased with them, especially the feeling of power transfer with the stiffer sole, (compared to my other shoes). Seem to do a good job of not letting muck in too.
Size wise – Normal shoes Im a 44 in Spesh shoes a 45 but the M200s needed a 46.
My only minor complaint (not the shoes fault) is the left one is perfectly comfortable and dont even know I’m wearing it. On longer rides the right one gives me a little ache in the outside of my foot and despite several adjustments I still haven’t managed to eliminate it. Might be the footbed though.
Also, they work brilliantly with the XT pedals. They are designed to work with the long blocks either side of the cleat sitting on a flat part of the pedal cage. Once you get the set up right, there is only a very small amount of float. I’ve used the shoes with DX647 pedals too and were fine but just fantastic with the XTs.
HTH?
