Ways to lock my feet to the pedals, OR, Cycling shoe options for (really) wide feet I have very wide feet, like ridiculously wide. I found some data for Australian male foot sizes and I'm at the 80th percentile for length but the 99.7th percentile for width. I'm currently wearing shoes a size too long in extra extra wide, and they're still barely wide enough.

I've been road cycling for a while now, and I'm starting to take it seriously (looking for a club to join). I would like to be able to lock my feet into the pedals, but I don't know where to start. Old school around-the-toe straps are difficult because my regular shoes are too long, and as you might have guessed, off the shelf cycle shoes (at least the few that I've tried) aren't designed with someone like me in mind.

What options are there to lock my feet to the pedals so I can practice optimal pedaling technique? Some kind of shoes+clipless pedals approach is clearly the most common way to deal with this, but I'm willing to look at some more unusual or exotic solutions, whether that relates to the shoes, the pedals, straps, anything. Ideally with some kind of quick release mechanism because I'll be on the road.

As far as shoes go, this question is very similar, but it's over 9 years old and the linked pages don't exist any more. Plus, 9 years is plenty of time for more options to become available.
Lake makes several shoes in wide widths. I’m particularly partial to their sandals for my wide feet (but depending on what kind of club you’re aiming to join, they may not be the right look).
