This is a lot like the running shoes without built up heels that encourage you to run on the balls of your feet. Just like the X-country flats I ran in high school. I loved them! I could run miles with my heels barely touching. Never had shin splints. But early season was hard! That took training. Later years I tried running with the by then, universal padded and well heeled shoes. (They were a lot more expensive, making for well heeled CEOs also.) Shin splints were my nemesis and I never ran for very long. It was obvious both that the shoes made no heel-strike running near impossible and cycling had further allowed the muscles in the front of my foot to deteriorate a lot. Going from the moccasin shoe-like LL Bean boots to hiking boots didn't help.
I don't see these pedals for serious cycling. But I do see how riding them could be very beneficial to the foot. Might even be a gentle way to strengthen up to run in the new heel-less shoes. (For serious cycling, there are the exact opposite of sliding your cleat back to minimize foot issues.)
