PowerStep Pinnacle Maxx orthotic insoles M 9-9.5 — Maximum stability, firm arch & deep heel support

PowerStep Pinnacle Maxx are firm, medical-grade orthotic insoles that deliver increased stability, deeper heel support, and targeted cushioning to reduce discomfort from overpronation and flat feet.

These insoles upgrade the classic Pinnacle line with a stiffer shell and reinforced arch to give stronger control without sacrificing comfort. Designed in the USA, the Pinnacle Maxx pairs a squared, deeper heel cup and a 2° medial post with dual-layer EVA cushioning and a moisture-wicking polyester top layer. They come ready-to-wear—no trimming required—and are built to transfer easily between athletic, casual, dress, or work shoes where the original factory sockliner can be removed.

How do these insoles improve stability during daily activities?

The Pinnacle Maxx stabilizes the foot by combining a firmer arch and an angled heel post that reduces inward rolling. The squared heel design keeps the foot centered in the shoe, improving alignment through the ankle and knee. This makes them useful for walking, standing, and moderate activity where control matters.

• 2° medial post for controlled pronation correction
• Deeper, squared heel cup for enhanced rearfoot containment
• Firm shell maintains arch support under load
• Works across shoe types without trimming

Will these insoles be comfortable right away?

Yes—PowerStep designed the Maxx to balance firm support and user comfort from the first wear. The top layer is 100% polyester to reduce friction and wick moisture, while the dual-density EVA base provides shock absorption with a moderately soft feel over the rigid support core.

• Polyester top keeps feet dry and reduces rubbing
• Double-layer EVA for shock absorption and cushioning
• Firm-but-flexible construction for everyday wear
• Thicker Pinnacle option requires removable factory insoles for fit

What foot issues can these insoles help with?

PowerStep Pinnacle Maxx are intended to address mechanical issues tied to pronation and arch collapse rather than treat medical conditions. They’re commonly used to manage symptoms linked to overpronation, flat arches, and general heel or arch discomfort by improving foot positioning and distributing pressure more evenly.

• Helps control overpronation and arch flattening
• Supports improved heel and arch alignment
• May reduce stress on ankles and knees from poor foot mechanics
• Suitable for everyday footwear, including athletic and work shoes

How should I care for and replace the Pinnacle Maxx insoles?

Care is simple: spot clean with mild detergent and air dry—do not soak. The lifetime depends on usage and wear patterns; inspect regularly and replace when cushioning compresses or support degrades. These insoles are HSA/FSA eligible and made in the USA.

• Spot clean only; do not immerse in water
• Air dry; avoid heat sources
• Replace when EVA layers or arch support wear down
• Ready-to-wear—no trimming required for most shoes

Who is this for: The PowerStep Pinnacle Maxx is aimed at adults seeking firmer orthotic support—people with flat feet, mild-to-moderate overpronation, or those who spend long hours on their feet and need enhanced stability. It’s a good choice for shoppers who want a durable, ready-made insole that fits into a variety of shoe styles and offers immediate structural support without custom molding.
