I bought a crocs years ago for $5 bucks at the Dollar store.  Believe me they were ready for retirement. Couldn't believe how much they cost now.

I am never sure about ordering shoes on the internet.  My old crocs were size 5 and fit close to my long toe. So, I ordered a size 6.

With the strap down in back they fit my bare foot and I flip the strap forward and they fit nice with socks.

I really like these crocks and with the ventilation my feet don't sweat.

I am getting another pair.
