I bought these as my fist pair of shoes to go with my clipless pedals.  I had tried on other shoes at the bike store and found them to be very uncomfortable.  These, on the other hand, are superbly comfortable.
I had to problem installing the cleats-- it only took about five minutes.  These shoes are SPD (2 bolt pattern) compatible.
I usually wear a size 8.5 in athletic shoes and I ordered a size 41.  They fit perfectly.
