This may be the dumbest question asked in these forums (hopefully I'm in the right category), but I'll ask anyway. I'm not an elite cyclist, but enjoy cycling and planning on making it my preferred workout. I'm coming off of surgery on my right knee and my running days are pretty much over. I'm interested in purchasing the Assioma Dual Power Pedals just so I can monitor myself and know when I'm pushing my right knee to the limits. Now for the dumb question. Can these pedals be used with standard running shoes or are cleats required? Thanks for any advice in advance.
