No you can't. I tried that and they had $5 shoes you can rent. I never went there so I didn't know I couldn't wear sandals. But they have shoes and socks for you.
My buddy wore Keens. It's a heavy duty sandal. I wore old tennis shoes.
Depends on the type, I'd say Keen sturdy type would be OK.
No. It would be unsafe and painful.
You need closed toe shoes to participate. We have $5 rentals for those that need them.
