Can these mountain bike clips be mounted on a road bike shoe?
Some road shoes can use both two-hole SPD compatible cleats and typical three-hold Look style cleats. This is rare to find in upper end carbon soled road shoes. To determine if your shoe does support SPD client you should see two mounting holes about an inch apart that are allowed to slide fore and aft on the shoe for adjustment.
Depends on the Shoe
You need a SPD Compatible shoe
Most road shoes with Plastic souls will have slots for SPD cleats but few Carbon souled shoes will work
