Original yoga sandals size large which is 9.5” or less. See size chart Worn in house a few times. Yoga Sandals are uniquely designed to enable all toes to perform optimally; as good as barefoot. Because each toe is anchored into the sandal, the foot is well supported and our posture is also complemented by the contoured instep, which can help improve the stability of the body. The sandals relieve pressure on the instep and gently splay the toes thus easing pressure on the metatarsals.
