【Excellent Condition】Tadashi Kaneko Kaneko Stretch Foot Stretch Sandals Size: L～LL I wore these indoors for about two weeks. I've wiped them down with disinfectant wipes, but please refrain from purchasing if you are overly concerned about cleanliness. ※ The box is not included. 【Product Description】 Developed and supervised by Tadashi Kaneko, Stretch Trainer / Physical Therapist Prolonged desk work, smartphone use, narrow-toed shoes like heels and pumps, lack of exercise, and reduced time walking barefoot can diminish the original function of the soles of the feet. Kaneko Stretch Sandals address this issue and are designed to support a healthy and active daily life. ① Simply wearing them stretches your toes, soles, and heels! They also directly apply pressure to the soles of your feet. ② Wearing them forms the arch of your foot, allowing you to grip the ground with your toes. Just switch from your usual slippers! Turn your time at home into a foot stretch walk.
