And at least one rider here has done a fully loaded for camping short tour at 80+ miles/day wearing no shoes, on Ergon PC2 platforms.
This is what I came up with, here I am in Ireland back in July waiting for the ferry to get to Cobh the other side of the River Lee, Day 23 of a 40-day tour.
Single layer of nylon top and bottom; oversized Magellan fishing shirt, loose REI nylon "Adventure" (their term) pants tucked in ordinary dress socks. Nothing underneath. Crocs on my feet and that's a Brook's saddle on my bike (and note the mirror on the wrong side
).
I find the single layer of nylon thing works real well; comfortable to wear, dries very fast and you can't get sunburned through it even in summer. It has seen me comfortably through 100+F days here in Texas. With an ordinary Gortex raincoat as needed for rain and cold nylon like this also worked real well in the usual 40's to 70's temperature of Ireland and the UK in summer. This is also my usual commuting attire.
My sister tells me I look like a garden gnome
But hey, anything to avoid becoming what they called in England a MAMIL (Middle Aged Man in Lycra)
