I've worn through my first pair of Look cleats.  I was not having any issues with the worn cleats but figured I'd replace them before beginning to have issues.  Fortunately I had a spare pair on the shelf, thanks to a Christmas gift from mom and dad a couple years ago.

The new 3 cleat system.

The first ride of the year on the Litespeed had me feeling like I was pedaling with my toes.  I'm guessing it's from riding an indoor exercise bike so much over the winter, so I've shifted my pedals rear ward a touch. Actually they are shifted rear ward as far as possible with these shoes.

The wear dots on the old cleats were about gone.
