Thanks for jumping to a new thread ... I probably should have done that, myself.
Should we start with a definition of "proper cycling shoes" ? :-)
I have found the proliferation of pedals with large platforms to help me rethink what I am looking for in a cycling shoe. Of course, that also corresponds with retirement and never doing rides on which I feel the need to have my feet securely attached to the pedals. On the contrary, I am finding that being able to shift my feet around is significantly improving foot comfort on longer rides. It also has been helping me subtly alter the pedaling dynamics which is recruiting different muscles, which also reduces fatigue on longer rides. I did a 200km ride Saturday and being able to change my foot position was very helpful. I think that it's not just having a wider toe box, but also a more flexible sole that's important to foot health on long outings. My "theory" is that stiff soles, which are great for shorter rides with higher power output, are more damaging in the long run because they don't require the muscles (and attachments) in your feet and ankles to perform their usual stabilization and support functions. I'm not a PT/OT/MD, though, so take that for what it's worth.
Still, I appreciate the advantages of stiff soles and secure pedal connections. Unfortunately, I have yet to find cycling shoes that allow my forefoot to spread as much as it wants to, and the result has been painful bunionettes. My Lake MX-1 shoes, on their MX competition last, sadly discontinued, have been the best I've found. It also helps that they are tradition lace-up shoes. Well, helped ... apparently there's no market for that feature anymore.
Top tip for checking shoe fit. Pull out the insoles and stand on them. You'll immediately see the difference between the shoe shape and your foot shape. It's kind of scary, though ... fair warning!
