SlimTech ¾ combines the supportive design of our Original orthotics with the versatility of a ¾-length product. This orthotic is slimmer and thinner and fits most casual, slip-on, and dress shoes. Like the Original, it features a prescription-grade shell, stabilizing heel cradle, and anti-bacterial ETC top sheet. It also utilizes an exceptionally breathable Hypurcel® cushion top cover. SlimTech 3/4 is available in seven sizes
