Compare the picks and what to watch out for

What PowerStep insoles are

PowerStep sells over-the-counter orthotic insoles rather than soft comfort liners. The maker describes its Pinnacle insole as having a firm but flexible polypropylene support shell, a contoured neutral arch and a deep heel cradle for comfort, stability and motion control. Cushioning comes from a foam top layer over an EVA base, under an odor control polyester top fabric.

In its product guide, PowerStep lists the Pinnacle's support level as moderate, with semi-rigid arch support. That puts it between soft cushioning insoles and rigid custom orthotics. The maker says the Pinnacle is designed to relieve and prevent pain from plantar fasciitis, Achilles tendonitis and shin splints, and from mild to moderate pronation. Those are the maker's stated design aims.

Which one fits your foot

Sizing, trimming and break-in

PowerStep says the Pinnacle comes in 12 sizes, from men's U.S. 3 to 16+ and women's U.S. 5 to 12, and fits widths up to 2E. For 3E to 6E feet, the maker points to the Pinnacle Wide. The Pinnacle High comes in 10 sizes, from men's 4 to 15 and women's 6 to 12.

  1. Remove the shoe's factory insole. The maker positions these for shoes where the factory insole can be removed.
  2. Trim from the toe area only, using the factory insole as a guide, as PowerStep instructs for the Pinnacle.
  3. Ease in. PowerStep says most users adapt within 1 to 3 days. If yours feel firm, start with a few hours and build up.

The maker offers a 60-day guarantee on returns or exchanges, according to the Pinnacle page.

Who might prefer something else

A semi-rigid shell is not for everyone. If you want pure softness, a cushioning insole will feel kinder. If your shoes are shallow or you have a high instep, a full-length orthotic may crowd the top of your foot. And if you have a rigid or painful flat foot, a high arch that is new, or diabetes with reduced feeling, see a podiatrist before choosing any orthotic.

The picks below include non-brand alternatives for those cases.

What to look for when you buy

PowerStep Pinnacle (neutral arch)

Best for: Everyday heel and arch pain with mild to moderate pronation

PowerStep Pinnacle Maxx

Best for: Noticeable overpronation or flat feet that roll inward

PowerStep says the Maxx adds a firmer shell and a 2 degree medial heel post to limit inward rolling.

Watch out: Firmer and more corrective than the standard Pinnacle; not aimed at high arches.

See options on Amazon

Non-brand alternative: semi-rigid arch support insole

Best for: Anyone who wants the same type of support from another maker

Semi-rigid shells with a deep heel cup are a common over-the-counter design; compare arch height and width ranges.

Watch out: Arch shapes differ a lot between makers; check the return policy.

See options on Amazon

Non-brand alternative: cushioning insole with mild arch

Best for: People who find orthotic shells too firm

A softer foam or gel insole adds comfort without the stiffness of a polypropylene shell.

Watch out: Less arch control and compresses faster.

See options on Amazon

Non-brand alternative: silicone heel cups

Best for: Heel-only pain or shoes with no room for a full insole

A small heel cup cushions the heel and fits in most closed shoes.

Watch out: No arch support.

When to talk to a doctor: Over-the-counter orthotics are for comfort and support, not diagnosis. See a doctor or podiatrist if foot pain lasts more than a few weeks, or if you have numbness or a newly flattening or rising arch. If you have diabetes, check your feet every day and contact your provider about any sores, redness or swelling, as MedlinePlus advises.
