For the average person using a rowing machine, it’s generally a good idea to wear shoes for indoor rowing to utilize stability, comfort, and grip provided by them and protect your feet.However, you may see some athletes opt to row barefoot. These are usually people who practice outdoor rowing, where wearing minimalist water shoes or no shoes is more common. Barefoot training has its benefits, but it also carries a higher risk of injury and exposing your feet to harmful bacteria found on the floor.
