My 10 years' experience in cycling tour has taught me in travelling light. Wet socks soften and weaken the skin, making feet vulnerable to blisters.

I will pull out my shoe bag (5" x 9" x13") from my motorcycle Uglybros seat bag which contains

Jeans x1
Underwear x 3
Socks x 2
T shirt x 3
Short pants x 2

One 72 yrs old cyclist in our group just brought 1 pair of underwear. Saw him walking around in his hotel room in his underwear only. He cycled with his wet jersey and shorts.
