I bought a pair of Shimano SH-MT33L Mountain Bike Shoes for a spinning class at my local gym. After attaching a pair of SPD cleats I find that it takes great effort to clip in and out...way too much resistance. I tried them on different X-bikes at the gym and same thing. I can clip in and out but its way too tight, to the point that the cleats actually get misaligned. I noticed that the cleats sit below the shoe rubber and are not touching the ground when I walk. I am wondering if the problem may be due to the rubber pressing down against the pedal, creating too much resistance, because the cleats are not exposed enough. Any ideas?
