PerseveranX vs PowerStep: An Honest Comparison
Share
Same disclosure as always: we make one of these. Check what we say.
PowerStep is a different kind of competitor to write about than most, because their main strength is not a material or a shape. It is that they make it hard to buy the wrong one.
Where PowerStep is genuinely strong
They publish arch heights and tiers. Low, standard, High, Maxx — across the Pinnacle range, you can find the shape that matches your foot without guessing. In a category where most brands publish nothing, this is a real service and it is the single biggest reason people get a good result with them.
Easy on day one. The semi-rigid shell with a cushioned top layer is the most forgiving of the firm options. Plenty of firm insoles require a week of commitment before you know. This one does not.
Clinic distribution. Widely recommended by podiatrists and physical therapists, which means a lot of people arrive at it through someone who examined their feet — a better path than reading an article, including this one.
Targeted models. The Maxx has a built-in medial post for heavy overpronation. That is a specific solution to a specific problem, and if that is your problem it is worth going straight there.
If you are buying your first supportive insole and do not know your arch height, PowerStep is the lowest-risk purchase in this category. We would say so even if we did not make insoles.
Where we are different
1. Durability under sustained load
Getting the right shape solves the first month. It does not solve the sixth.
Every insole compresses under load. The question is whether it returns. We build on open-cell foam — interconnected cells, air moving in and out, material displacing rather than crushing, returning toward its original height between steps.
The category standard is closed-cell foam: sealed gas bubbles that buckle permanently under repeated load. Pack-out. The support does not get softer, it gets shorter, and it is slow enough that most people blame their feet.
We have not tested what is in a PowerStep and will not claim to know. What we will say is:
Press the arch of both hard with your thumb. Hold two seconds. Watch what happens when you let go.
That test is free, takes no expertise, and works on every brand including ours. Here is what you are looking at.
2. Two different answers to the same problem
Both of us are trying to give you a support that fits and does not feel punishing. We do it differently.
PowerStep's answer is arch height selection — pick the tier that matches your arch, and it fits because it was the right shape to begin with.
Our answer is a support frame that gives. One arch height, but the TPU frame under the foam is open through the middle — a U rather than a solid plate — so it carries load along the edges of the arch and flexes as your arch loads through a step. Above it, your foot rests on foam rather than on the frame.
Their approach is more precise. Ours is more forgiving. If you know your arch height, precision is worth more. If you do not, or if you fall between tiers, forgiving is worth more.
3. Choosing by day, not by foot
PowerStep's line is organized by arch height and support level. Ours is organized by what your day does to your feet — softest for sore spots, highest rebound for walking miles, impact-responsive for ladders and stairs, thinnest for dress shoes, deepest cushioning for standing shifts.
Different questions. Theirs: what shape is your foot? Ours: what does your day do to it?
Where we are behind
Published arch tiers. They have four. We have one. If your arch is low, we do not have a version for you and they do.
Clinical relationships. Decades of distribution through podiatry and physical therapy practices. That is trust we have not earned yet.
Reviews and history. Same as with anyone established. If long-term evidence is what you weight, that argument goes to them.

The one-line version
If you do not know your arch height and want the safest first purchase, PowerStep's published tiers are hard to beat and we would point you there.
If you have the shape sorted and the problem is that support keeps going flat on you, that is what we built for.
Thumb-test both. It is the only test in this category that does not depend on believing anyone.
