10 Best Insoles For Knee Arthritis 2026 in the United States

The PowerStep Pinnacle Pink orthotic insoles are a solid choice for women seeking relief from foot and knee discomfort related to conditions like plantar fasciitis and arthritis. They offer strong arch support with a firm yet cushioned design, which helps stabilize the foot and reduce stress on the knees. The deep heel cup is a standout feature, providing extra support that can help control pronation (the inward rolling of the foot), which is often linked to knee pain. Made from comfortable polyester and EVA materials, these insoles deliver good cushioning without feeling bulky.

One convenient aspect is that they come in specific shoe sizes for a good fit right out of the box, so no trimming is needed. This can be a big plus if you want an easy-to-use insert that works in casual shoes like flats or boat shoes. Since they are designed for daily use, the PowerStep Pinnacle insoles are durable and backed by a solid warranty, giving you confidence in their long-term support.

On the downside, the moderate level of support might not be enough for people with very severe foot or knee problems who need custom orthotics or firmer support. Also, while they fit many shoe types, they may not be ideal for very tight or specialized footwear. These insoles provide a good balance of comfort, support, and convenience, making them a practical option for women looking to ease foot and knee pain without complicated adjustments.

The PowerStep Original Insoles are designed to provide firm arch support and cushioning, which can be beneficial for those dealing with knee arthritis by helping improve foot alignment and reduce strain. They feature a full-length design with a deep heel cup that offers stability and helps control foot motion, important for reducing stress on the knees. The dual-layer cushioning balances comfort with a slim profile, making these insoles suitable for tighter or dress shoes. Made from ethylene vinyl acetate and polyester, the materials are durable yet flexible, allowing for some give while maintaining support.

These insoles come in specific sizes (men's 8-8.5, women's 10-10.5), so sizing is important to ensure a proper fit, as a poor fit could reduce their effectiveness. The orthotic design aims to relieve mild to moderate foot pain related to conditions like plantar fasciitis and mild pronation, which can indirectly support knee health by improving foot mechanics. They might not provide enough cushioning or support for severe knee arthritis cases, and their thin design may not suit those needing more padding.

The included odor-control fabric enhances comfort during extended wear. For individuals needing everyday support in low-profile shoes who have mild symptoms, these insoles provide a reliable option backed by a 60-day guarantee and lifetime warranty on the arch support.

The PowerStep ProTech Orthotic Insoles offer strong arch support and a full-length design that help stabilize your feet and may reduce stress transmitted up to your knees—important for those dealing with knee arthritis. They provide semi-rigid arch support, which is effective for maintaining proper foot alignment and can ease knee pain caused by uneven walking patterns. Cushioning is a highlight, featuring maximum padding and a specialized ShockAbsorb foam heel cup that softens impact to make walking or standing more comfortable.

Made in the USA, these insoles fit a variety of shoe types including work boots, dress shoes, and sneakers, enhancing their versatility. The fit is specified for men's size 9-9.5 and women's 11-11.5, so selecting the correct size is essential for comfort and effectiveness. The orthotic design supports common foot issues like plantar fasciitis and also benefits knee arthritis by improving overall foot function.

A potential drawback is the limited size range, which might not accommodate everyone, and the semi-rigid arch may feel firm for those who prefer softer insoles. The lifetime warranty on the arch support and 60-day satisfaction guarantee provide added assurance. These insoles are ideal for anyone seeking durable, supportive inserts that combine cushioning with structural support, especially if experiencing knee discomfort related to foot alignment problems.
