If you have Eggbeaters pedals and not using these shields your cycling shoes are taking a heavy beating. They don't interfere with clipping in or out , and I love the metal to metal click they make letting you know that you're clipped in securely .
i wish i knew about this product sooner. i have crank bro peddles on three of my bikes, and 2 pairs of shoes. the pedals have worn into all four of my shoes under the cleat. this product makes a solid place for the pedal to contact instead of wearing into the carbon sole
Installed Shoe Shields on Sidi Dominators and Spiders. Not only do they protect the sole, but they also provide better spacing and durability than the flimsy spacers that come with the Sidis. The plastic spacers got bent up pretty quickly, which actually made clipping-in difficult. Shoe Shields cured this problem.
I don't have carbon soled shoes. However, I purchased these in hopes that they would stop the annoying creaking noise coming from my cycling shoes when riding on regular Eggbeaters. They work well and are inexpensive to boot. Some people say that the shields make it harder to clip in and out of the pedals, but I haven't noticed any difference in that area.
