A heel lift adds elevation beneath the rear of the foot. An orthotic insole provides a shaped support surface beneath more of the foot. A medial or lateral heel wedge raises one side of the heel relative to the other. Start with the change your fitting plan requires: height, support, directional positioning, or cushioning.
Our adjustable heel lifts, full-length orthotic insoles, and Warwick heel-wedge listing illustrate those different designs. They belong in the same footwear conversation, but a similar outline or the word "orthotic" does not make them interchangeable.
Ask one question before ordering: what is the insert supposed to change? A request for a particular height is not the same as a request for an arch contour or a side-to-side angle. Some professionally fitted devices combine those functions.
Compare the four main insert functions.
The American Academy of Orthopaedic Surgeons describes orthotic devices broadly, including supports, wedges, and cushions. In this guide, "orthotic insole" means a contoured footbed, while "medial or lateral wedge" means a side-to-side adjustment.
| Insert type | Main function | Information to confirm | Do not assume |
|---|---|---|---|
| Heel lift | Elevates the heel within the shoe, usually with a taper toward the front. | Required height, adjustment steps, side, footprint, and shoe depth. | A taller lift provides more useful arch support or replaces a full-sole raise. |
| Orthotic insole | Provides a contoured surface for support and pressure distribution; some designs also cushion. | Length, arch contour, shell flexibility, heel cradle, and forefoot features. | Every insole supplies a specified correction height or is custom-made. |
| Medial or lateral wedge | Introduces an incline across the heel or another specified region. | Angle, thicker-edge orientation, left/right use, and intended placement. | A wedge angle can be substituted for a heel-lift height. |
| Heel cup or cushion | Cradles or cushions the heel, depending on its construction. | Material, shape, thickness, and purpose. | A soft pad maintains the same elevation as a firm height-adjustable lift. |
Why the term “heel wedge” needs clarification
A heel lift can look wedge-shaped because it slopes from back to front. A posting wedge instead changes the relative height of the inner and outer sides. This is why a request that says only “heel wedge” needs a model, measurement, and orientation before it becomes an order.
"Medial" means the inner side, toward the other foot; "lateral" means the outer side. For a directional wedge, confirm which edge is raised in the intended shoe. Do not infer that orientation solely from the location of pain, uneven shoe wear, or a general label such as “pronation.”
The Warwick manufacturer specifies a reversible 4-degree wedge. Our Small Warwick heel-wedge listing, reference 576_S, provides an example of an angle-based product. Check its current availability and size information before ordering. Reversible does not mean that every orientation is appropriate for the same person.
Four degrees is not four millimeters. Degrees describe an angle; millimeters describe a distance. An inclined surface's edge-to-edge height difference also depends on its width. Preserve the original specification instead of trying to exchange an angle for a familiar lift height. Our heel-lift height chart handles millimeter-to-inch conversions once a height has been established.

| Product | Published design | Question it helps answer. |
|---|---|---|
| Balego Adjustable Heel Lift | Extra-firm foam with a suede top; three nominal configurations: 1/8, 1/4, or 3/8 inch. Sold individually. | Does the intended heel-elevation plan match one of these three settings? |
| Clearly Adjustable Heel Lift | Firm, clear vinyl; published 1–12 mm range in 1 mm steps. Sold individually. | Is a finer height increment needed, and does the selected footprint fit the shoe? |
| Warwick Heel Wedge—Small, 576_S | 4-degree directional wedge; the linked listing is one small wedge, not a pair. | Has the wedge angle, orientation, and size been specified? Confirm availability rather than substitute a lift. |
| SoleAid Work III Orthotic Insoles | Full-length design with a medium-flex support shell and layered cushioning. | Is the goal a replacement contoured footbed for suitable work footwear rather than a measured heel raise? |
| SoleAid IV Cork Blend Orthotic Insoles | Neoprene cushioning, a medium-flex shell, and a cork-EVA blend base. | Does this support structure and material combination suit the required shoe setup? |
| SoleAid I+ Metatarsal Insoles | Full-length support with a built-in metatarsal pad, arch contour, and heel cradle. | Is integrated forefoot support required, and does its location match the foot? |
These are examples from our orthotic insoles, shoe inserts, heel lifts, and wedges collection. A metatarsal feature supports a different region from a heel lift. A cork-blend base describes construction, not an additional millimeter setting or a guaranteed degree of correction.
Can you use a heel lift with an orthotic insole?
Sometimes the fitting plan calls for both elevation and support. The question is not simply whether the pieces fit inside an empty shoe: the assembled system must still accommodate the foot, retain the heel, and position the support as intended.
Follow the instructions for the particular products and the clinician managing any prescribed orthosis. For example, Clearly Adjustable normally goes beneath the existing insole or footbed. That direction is specific to its design; it is not blanket permission to place every lift under every rigid orthotic.
Adding a separate component can change how the original contour sits beneath the foot. Do not grind, cut, or add a wedge to a prescribed orthosis without the provider's guidance. Some requirements are better incorporated into one fitted device than assembled from unrelated retail inserts.
A replacement full-length insole also occupies space. Where the footwear allows it, removal of the original liner can make room; stacking two complete footbeds is not a default way to obtain more support. NHS orthotics guidance emphasizes adequate shoe depth and width and following the orthotist's instructions.
With open footwear, retention becomes a separate issue. Read our heel lifts for sandals guide for fixed versus removable footbeds and strap-related checks rather than transferring a closed-shoe arrangement unchanged.
Check the complete shoe-and-insert fit.
Compare the chosen component with the actual shoe, usual sock, and any existing orthosis. The following are practical fitting prompts, not a method for diagnosing a leg-length difference or selecting a corrective wedge.
| Check | What to look for | When to pause |
|---|---|---|
| Heel retention | The heel remains seated within the shoe's intended supporting area. | The added component leaves the heel slipping or perched too high. |
| Support location | The arch contour and any forefoot feature sit where the fitting plan intends. | A prominent ridge or built-in pad presses in the wrong place. |
| Available space | The toes have room, and the fastening works normally. | Crowding, pressure, or instability appears after adding the insert. |
| Component stability | The layers remain seated without rocking, curling, or migrating. | The orthotic bridges over the addition or the parts shift during use. |
| Skin and comfort | Wear is introduced according to the supplied or clinician-directed plan. | Pain, numbness, persistent pressure marks, rubbing, or broken skin develops. |
Changing shoe size alone does not resolve every support-position problem. Likewise, trimming the outline of an insole cannot relocate an integrated metatarsal pad relative to its heel cradle. Our SoleAid I+ fitting information explains that model-specific distinction.
Turn an incomplete request into the correct order.
“I need a lift” still leaves the amount, side, and footwear unspecified. “I need orthotics” does not identify the contour, material, or whether a custom device was intended. “I need a wedge” leaves its direction and angle unresolved.
Before purchasing, have the product type or exact model, required height or angle, left/right instructions, shoe type, and existing inserts available. Check whether the price is for one component or a pair. Our two adjustable heel-lift listings are sold individually; buying a pair does not establish that both feet should receive the same change.
For replacement orders, preserve the complete model name rather than relying on appearance. SoleAid Work III and standard SoleAid III are different constructions. Send our product-support team the listing or package reference when the name is unclear. We can help identify published product details; diagnosis and the amount or direction of correction belong with the treating professional.
Frequently asked comparison questions
Is an orthotic insole the same as a custom orthotic?
No. A ready-made contoured insole is not an individually fabricated prescription device. The American Podiatric Medical Association distinguishes prepackaged inserts from prescription custom orthotics. Selecting a shoe size, trimming an outline, or allowing a material to conform through wear does not make a retail insert custom-made for a diagnosed problem.
Will a heel lift correct my arch or stop my foot rolling?
A lift's stated height does not specify an arch-support shape or medial/lateral posting. Some fitted devices include several features, but do not assume that heel elevation alone provides the correction described in an orthotic or wedge order.
Can I replace a worn heel lift with a soft gel heel pad?
Not merely because the products look similar. Cushioning, cradle shape, and maintained elevation are different specifications. Match the required function and the replacement product's documented construction rather than assuming equal height from an unloaded thickness measurement.
Should I use one insert or two?
Follow the established fitting plan. A one-sided lift, matching bilateral raises, and different corrections for each foot are different arrangements. Package quantity and a product's ability to fit either shoe do not decide which arrangement is appropriate.
Does heel pain tell me which type to buy?
No. “Heel pain” describes a symptom, not a measurement or diagnosis. Persistent pain or an uncertain correction deserves assessment before adding height or directional wedging. The California Podiatric Medical Board cautions that improperly fitted inserts can cause problems, particularly when diabetes or another condition increases foot risk. Seek clinical advice for reduced sensation, poor circulation, or a foot wound before changing the setup.
Choose the function first, then the product.
Use the three-layer Balego lift or clearly adjustable lift when comparing documented heel-elevation options. Review our orthotic insole and wedge collection when the requirement concerns broader support or directional positioning. Keep the exact requested specification and confirm the complete footwear fit before ordering.
Our heel-lift and shoe-insert guides cover the related sizing and footwear questions. A well-identified order starts with the intended change—not simply the smallest insert or the softest material.
