If you will be walking on wet or slippery surfaces, you will need flip flops with deep grooves or rivets on the soles.

This is important for preventing foot odor and blisters, especially when wearing the flip flops for extended periods of time.

Anti-slip flip flops are often made from breathable materials

This is a good option if you are looking for the ultimate in slip resistance.

Some anti-slip flip flops have rivets on the soles that help to provide additional traction.
