SPD single release vs. multidirectional release cleats??
If I understand correctly, single release cleats will only release when you kick your heal outward. Multidirectional must mean that they release when the heal is kicked outward or inward. The shimano SPD SH-51 cleats are "single release." The shimano SPD SH-56 are "multidirectional." I've been riding the multidirectional, but realized that I bought replacement cleats that are "single release." Is there an advantage to one over the other?
I'm using these cleats on mountain bike shoes (I enjoy being able to walk in my shoes) that I use on a touring bike as well as a road bike that takes SPD cleats. The shoes/cleats are not being used for any mountain bike specific purpose.
