Pictured below are the soles of two shoes. The top shoe is my Lake MX-165 mountain bike shoe that cradled my feet on the Coast to Cactus Tricycle Expedition, as well as other numerous rides. The shoe is very comfortable, and after I’m in them for a while, I forget they are cycling shoes. The Lake shoe is also very heavy, due in large part to the massive and stiff Vibram sole, although it still allows for too much nerve and blood vessel compression for me, an issue that continues to plague my feet with hot spots and numbness.
The other sole is that of my new SIDI Dominator 5 mountain bike shoes, which will take me on my upcoming expedition, and if they prove to be everything everyone tells me they are, may well become my permanent shoe of choice. Time will tell. They too are very comfortable, and easy to walk in despite the hard nylon sole due to their curved design that allows the foot to rock forward as you push off. The SIDI shoe is very light compared to the Lake shoe. I am hopeful that the non bending sole will allow my feet the freedom from nerve and blood vessel compression issues. One expedition will be all it takes for a verdict. Check back later this year.

Thanks a million! I am investigating Lake MX shoe now. Hurry up and test the SIDI.
