PowerStep Pinnacle Maxx Orthotic Insoles M 9-9.5 / W 11-11.5 — Firm Support, Angled Heel for Overpronation

PowerStep Pinnacle Maxx insoles are firm, double-layer orthotic inserts designed to deliver stable arch support, a squared angled heel, and durable shock absorption for daily comfort and improved foot alignment.

The Pinnacle Maxx builds on PowerStep’s Pinnacle line with a firmer shell and reinforced arch support for more control without sacrificing cushioning. Constructed with a deep heel cup, a 2-degree medial post, and premium dual-layer EVA foam, these insoles fit straight into most shoes without trimming and are crafted in the USA from a 100% polyester top fabric that helps wick moisture and reduce friction.

How do these insoles deliver extra stability for overpronation?

The Pinnacle Maxx combines a firmer arch core and a slightly angled heel post to limit inward rolling and improve foot positioning. That configuration increases medial support while the squared heel keeps the insert seated and stable inside the shoe.

• Firm-but-flexible shell for controlled motion
• 2-degree medial post for corrective support
• Squared heel design for anti-roll stability
• Deep heel cup to center the heel and maintain alignment

What cushioning and materials are used for daily comfort?

PowerStep used a double-layer EVA foam base with variable cushioning to provide targeted shock absorption from heel to toe. The top layer is 100% polyester to help keep feet dry, reduce friction, and feel comfortable throughout the day.

• Durable EVA base for long-lasting shock absorption
• Variable cushioning zones for targeted comfort
• Polyester top cloth that resists heat and friction
• Thicker Pinnacle profile suited for shoes where factory insoles can be removed

Will these fit my shoes and require trimming?

The Pinnacle Maxx comes ready-to-wear and fits a wide range of footwear styles without trimming, provided the shoe’s original insole can be removed. Their thicker profile is best in shoes with removable footbeds such as sneakers, work shoes, and many casual or dress shoes.

• No trimming required for the listed sizes
• Designed to transfer easily between multiple shoe types
• Best used in footwear with removable factory insoles
• Available in gendered sizing: M 9–9.5 / W 11–11.5 for a snug fit

How should I care for and replace these orthotics?

Spot clean with a mild detergent and avoid immersing the insoles in water; air dry only. Replace them when you notice visible wear, decreased cushioning, or reduced support to maintain performance.

• Spot clean only; do not submerge
• Air dry—no heat or machine drying
• Replace as needed depending on activity level and wear
• HSA/FSA eligible in many plans; verify with your provider

Who is this for: The PowerStep Pinnacle Maxx is ideal for people seeking firmer arch support with breathable top fabric and a deeper heel cup—especially those with overpronation, flat-feet tendencies, or anyone wanting a heavy-duty insole that stays put in everyday shoes. Recommended by clinicians for mechanical support (not a medical treatment), these insoles suit active professionals, walkers, athletes who need stable control, and anyone rotating orthotics between multiple pairs of removable-insole footwear.
