RX 3/4 Custom Arch Orthotic Insole

The Spenco RX 3/4 Custom Arch Orthotics are designed for people who want their shoes to feel better—whether you’re on your feet all day, getting back into a routine, or simply looking for more comfort. Built with SpenCore shock‑absorbing cushioning, they help protect your body from the constant impact that can lead to discomfort and overuse‑related injuries. The flexible heel and arch plate gently molds to your foot, giving you support that feels personalized and helps promote more controlled movement. This tailored fit can also help reduce the chance of painful injuries from happening in the first place. To keep things comfortable throughout the day, the top cover reduces friction to help prevent blisters and irritation, while Silvadur™ treatment controls odors and helps inhibit the growth of bacterial odors. Diamond‑shaped air channels move warm air away from the bottom of the insole to create a more breathable feel inside your shoes. Because they’re 3/4 length and low‑profile, these orthotics slip easily into a wide range of footwear without crowding your toes. With more than 35 years of trusted performance and millions of pairs sold, they deliver reliable comfort backed by the APMA Seal of Acceptance.
