OR…..bring a pair of flip flops you can easily slip on if you’re going to be walking around a bit. They’ll fit in your jersey pockets. Or….You could just carry your shoes on that 50yd walk from the shed to the road while wearing the flip flops and then just leave them there in the grass or behind a bush until you get back.

I’ve got the same type cleats and I get a couple years out of them, and that’s riding 7-10,000 miles per year, but I almost never walk further than about 20’, from the store front to the bathroom to the ice machine and back to the bike, on a smooth tile floor. I wear flips in the garage while getting ready and put my bike shoes on just 5’ from my bike, take 3 steps and I’m riding.
