Details
If you’re looking for an insole that offers support without changing the way your shoes fit, the Spenco Rx 3/4 Custom Arch Thin Orthotic Insole is built to make everyday movement feel easier. SpenCore shock‑absorbing cushioning helps protect your body by reducing impact, while the 3/4‑length design keeps your shoes feeling roomy and natural. The flexible heel and arch plate is designed to mold to your foot over time, giving you customized support and foot motion control that helps reduce heel and arch pain. A carbon weave plate adds structure without adding bulk, helping the insole stay thin while still offering dependable support. Comfort details are built in, too. The low‑friction top cover helps limit rubbing that can lead to discomfort or blisters, and Silvadur™ odor control treatment helps prevent the buildup of odor‑causing bacteria. Diamond air channels underneath the insole help move air through the bottom of your shoe for added breathability. Sized options help you get a better fit with minimal trimming, and the low‑profile construction works well in a wide variety of shoes. With more than 35 years of trust behind it, over six million pairs sold, and the APMA Seal of Acceptance, this orthotic delivers support you can rely on day after day.
