Walking barefoot should always be started carefully; a short walk of around 15 minutes several times a week is an ideal introduction. The foot muscles are usually not used much when wearing regular shoes and therefore need to build up slowly. This affects the muscles, tendons, ligaments and the particularly sensitive skin on the feet. It is therefore advisable to start with short walking or running routes first.
If you develop sore muscles, it is better to take a break for a few days before continuing barefoot walking. Once the muscle soreness has passed, you can slowly increase the distances and running times. All sock shoes have a protective function. Switching excessively from conventional shoes to sock shoes will never make sense.
