Don't knock flip flops. I wear thin soled flip flops (not the $1 plastic ones) because they give me the extra freedom for toe grip needed for balance. I can't feel what I'm walking on and lose my balance with closed in shoes with thick soles. I drive barefooted and am barefooted at home. Gardening is done barefooted for stability.
You WILL end up with Plantar Fasciitis. That is how I got it. The toe grip on flip flops. It causes the condidtion. Good luck.
