This is the first pair of cycling shoes I have owned.  They work very well and definitely improve my performance on the bike.  However, they do not keep your feet warm on cold morning rides.  Also, make sure the screws are very tight on the cleats.  If they come loose, it is extremely difficult to become unattached from the pedal - check the tightness of the screws frequently.

And the size may run a slight bit below stated size.  Not being used to the EU sizing, I ordered what it stated and they are a tad small.  They fit okay - but not enough room to double up on socks for the cold morning rides.
