- Improved foot structure and toe alignment: curved slit design reduces pulling pressure and supports movement mechanics. It eases toe discomfort, reduces overlap between the big toe and the second toe, aids toe separation, and helps with hallux valgus and bunions while guiding the big toe back toward proper position for balanced toes. - Adjustable size and universal fit: elastic material with adjustable tightness to suit most adult men and women. One size fits most feet. - Multi-scene wear: can be worn in shoes and socks; suitable for walking, running, yoga, and sleeping. Day and night use with no specific time requirement. - Nighttime relief: soft silicone cushion provides moderate support during sleep; relieves pain from hallux valgus, hammer toes, and crooked toes, helping them straighten over time. - Protective and corrective function: built-in silicone pad reduces shoe irritation and friction around hallux valgus; the toe separator applies a straightening force, aligning toe direction to promote an overlap between the big toe and the second toe and prevent misalignment.
