LOOK unsuccessfully marketed an offroad pedal & shoe years back which used
a cutaway LOOK cleat that only fitted their mtb shoe. Aluminium cleats
followed a few years later from the States but they've disapeared, another
US? company called Winwood made some cleats which didn't seem to wear that
quick, but they disappeared too!

Nowadays your choice is limited to cleat covers or maybe some of those new
carbon-fibre LOOK cleats made by Exustar.
