I have them (the MKS Lambdas) on 3 bikes. Our LBS has started stocking them after I had him order me my last ones. They aren't wide, so they don't strike the pavement on turns, but they are long, so they provide a nice platform for riding. They completely solved my burning foot issue. I've ridden them with hiking boots in the middle of winter, sneakers, mtb shoes and even keen canvas sandals. Have I mentioned that I LOVE them?
