Walking without slippers and shoe results in some health benefits.
Wearing shoes weakens the muscles in the feet. Wearing flip flops with little support in the arch and heel strain and stretch the fascia and Achilles tendon, damaging them. Wearing silts causes the calf muscles to tighten up ht pull the ligaments and tendons, altering the gait. Walking barefoot on the other hand exercises the toes and arches and thereby improve shock absorption and balance, and possibly prevents injuries as well. Walking barefoot, especially on sand or grass, recruits more muscles that help stabilize the food.
Shoes that cover the feet prevents the feet from being in contact with the outside temperature and could cause the sweat to concentrate on the sin pores, causing sin damage and other negative effects. Walking barefoot provides the much needed air circulation for the feet. Worn out soles cause the additional risk of the skin contacting diseases like plantar fasciitis, caused by inflammation of the tissue band connecting the heel and the toes.
Walking barefoot however may cause serious side effects for those suffering from arthritis an diabetics, and such people should walk barefoot only after consultation with their medical practitioner.
It I always a good practice to walk barefoot at home, and in the office if possible.
