Choosing between PerseveranX and Superfeet starts with the shape and space your shoes need. Superfeet offers several arch heights, thicknesses and activity-focused designs. PerseveranX offers five distinct cushioning feels built around a shared full-length support concept. If shaped arch support fits your foot, your preferred feel becomes an important part of the choice.
The most useful comparison is between two specific models in the same pair of shoes. Here is how to make that comparison practical.
Where the selection approaches differ
Superfeet's range includes low-, medium- and high-arch options, with different thicknesses and cushioning characteristics. Its own arch-height guide puts emphasis on comfortable contact and available shoe space, rather than choosing by arch height alone.
PerseveranX keeps the support concept consistent across five models: open-cell PU cushioning above a contoured EVA comfort base and a firm TPU frame that supports the arch and cradles the heel. The main choice within our range is cushioning response. Moving from Embrace to Fusion changes the feel, not the collection into a different arch-height category.
What are you trying to change in your shoes?
If your current insert feels too easy to sink into, look for firmer cushioning. If it feels hard where your foot meets it, look for a more yielding contact layer. If your heel rises too high in the shoe, check the entire insert's profile and the available room before comparing softness.
Embrace offers soft contouring with low bounce. Fusion offers a more substantial cushion with less sink than Embrace and a similarly low-bounce character. These are two clear starting points for someone who wants shaped support and is deciding how much give to feel above it.

Compare these five things in person
- Arch placement: does the curve meet your arch comfortably rather than pressing into one small spot?
- Heel seating: does your heel remain secure inside the shoe's own heel area?
- Toe space: can your toes move without being pushed against the upper?
- Cushion response: does standing and walking feel softly yielding, firm or springy in the way you prefer?
- Fit after trimming: does the insert lie flat without buckling or sliding?
Use your everyday socks and remove the factory liner where it is designed to come out. If you need an unusually wide fit, compare actual dimensions: Superfeet lists dedicated wide-fit products in its product FAQ, while our wide-feet guide explains how to check the available platform.
Why consider PerseveranX?
Consider PerseveranX when you want a defined arch-and-heel foundation with a deliberate choice of cushioning response. Our open-cell PU materials are selected for shape recovery and resistance to lasting flattening, helping preserve the cushion you chose through repeated wear.
Each model has approximately 0.16 in (4 mm) of cushioning. The contoured EVA base is approximately 0.04 in (1 mm) beneath the forefoot and thicker at the heel. Check those layers as part of the complete fit, rather than assuming a firmer model is thinner.
There is no single winner for every shoe or foot. Choose the model that meets your shape and gives you the response you want to return to each day. Find your PerseveranX feel, then check the size before ordering.
