The ankle does several things at once during a step. It absorbs the shock of heel contact, lets the foot rotate down flat, provides a stable platform through midstance and pushes off at the end. A prosthetic foot has to approximate that with whatever mechanism it carries, and the SACH design does it with none.

SACH stands for solid ankle, cushion heel, and that describes the whole mechanism. There is no articulation at the ankle, no axis and no bumpers. Instead a compressible wedge of foam sits in the heel, and when the heel contacts the ground that wedge compresses. The effect resembles plantar flexion, bringing the foot to flat without any joint having moved, which is why it is often described as pseudo-plantar flexion.

Behind the heel wedge runs a rigid keel, in this case wood, encased in polyurethane. The keel gives the foot its shape and its stability through midstance, and it is what the user's weight passes over as the body moves forward across the foot.

What follows from that construction is simplicity. With no moving parts there are no bumpers to foul with dirt, no axis to wear and no mechanism to service, which is why the design has remained in continuous use for decades and is the foot most widely fitted worldwide. It is light, and its durability comes from having little that can fail.

Heel firmness is the design's main variable, and it deserves attention at selection. A softer heel yields more readily at heel strike, while a firmer one resists. For a bilateral fitting this matters particularly, since soft heel cushions on both sides can leave a user with a tendency to fall backwards, and firm cushions are indicated. That is a clinical judgement for the prosthetist, and the heel options available on this foot should be established.

Heel height is the other practical variable, because a foot built for one heel height suits a narrow band of footwear. A user who wears different shoes needs that accounted for at fitting.

The foot is supplied in sizes across the adult range in polyurethane, in beige and brown finishes, with published weights from 140 g to 650 g depending on size. It attaches to the prosthesis through a foot adapter, and the attachment method and compatible adapters should be established for the build.

This is a component rather than a finished prosthesis. It is selected, aligned and fitted by a qualified prosthetist as part of a limb assembled around the individual, and suitability, heel firmness and alignment are clinical decisions taken by that professional. The manufacturer, size range, per-size load rating, heel options, adapter compatibility and handing are provided by the seller at quotation, with UKCA or CE marking documentation, the declaration of conformity, instructions for use and warranty terms issued by the manufacturer or held by the seller.

Transtibial prosthetic fitting is the primary application, with the foot selected and aligned by a prosthetist within a complete limb.

Limited community ambulators and level-ground walking are the settings the SACH design has long been fitted for.

Users needing a durable foot with nothing to service are served by a construction with no bumpers, axis or moving parts.

Bilateral fittings require attention to heel firmness, since soft cushions on both sides can produce a tendency to fall backwards.

Users wearing footwear of a consistent heel height are accommodated by a foot built to that height, established at fitting.

Services fitting across a range of patient sizes are served by a size range spanning the adult foot, with the exact range confirmed.

Clinics holding stock benefit from a component that is light, durable and needs no scheduled maintenance.

An Ankle Function Without an Ankle

The compressible heel wedge produces the effect of plantar flexion at heel strike without any joint having moved.

Stability Through Midstance

The rigid keel gives the foot its shape and carries the user's weight forward across it.

Nothing to Service

With no bumpers, axis or mechanism, there is nothing to foul with dirt, wear out or maintain on a schedule.

Light on the Limb

Published weights run from 140 g to 650 g across the size range, which is carried at the far end of the prosthesis.

Durable by Construction

Longevity comes from having little that can fail, which is why the design has remained in continuous use for decades.

Heel Firmness as a Fitting Variable

Selecting heel firmness lets the foot be matched to the user, and it carries particular weight in bilateral fittings.

A Size Range Across Adults

Sizes span the adult foot, with the exact range to be confirmed from the manufacturer.

Finishes for Skin Matching

Beige and brown finishes are published, supporting a closer visual match under a cosmesis or sock.

Simple Attachment

The foot connects through a foot adapter, with compatibility established for the build.

Per-Size Load Limit Established

A maximum patient weight for the size supplied is obtained rather than a published band.

The 1F10 is a solid ankle cushion heel prosthetic foot in polyurethane over a wood keel. The ankle absorbs heel contact, brings the foot to flat, provides a platform through midstance and pushes off, and the SACH design approximates the first two of those with no mechanism at all: a compressible wedge in the heel yields at heel strike, producing the effect of plantar flexion without any joint moving, while the rigid keel carries stability through midstance. What follows is a foot with no bumpers to foul, no axis to wear and nothing to service, light at the far end of the limb and durable because there is little in it that can fail, which is why the design remains among the most widely fitted worldwide. Heel firmness is the variable that matters most at selection, and it carries particular significance in bilateral fittings where soft cushions on both sides can leave a user tending to fall backwards. Selection, heel choice and alignment are clinical decisions for the prescribing prosthetist. The size range, per-size load limit, heel options, adapter compatibility and handing are provided by the seller at quotation, alongside UKCA or CE documentation and instructions for use. Medigear.uk lists the foot for UK business buyers and can arrange supply, documentation and the provision of consumables. Enquire for a written quotation.

Frequently Asked Questions

It is a solid ankle cushion heel prosthetic foot in polyurethane over a wood keel, supplied as a component for a prosthetist to fit within a lower limb prosthesis.

Solid ankle, cushion heel. It describes the mechanism: no ankle articulation, with a compressible wedge in the heel doing the work.

The heel wedge compresses at heel contact, bringing the foot to flat in a way that resembles plantar flexion, while the rigid keel provides stability through midstance.

With no moving parts there are no bumpers to foul with dirt, no axis to wear and no mechanism to service, which is why the design is durable and widely fitted.

Polyurethane over a wood keel, in beige and brown finishes.

The manufacturer publishes 20–30 cm in one place and 15–29 cm in another on the same page, so the range should be confirmed before order.

Published as a range of 100–110 kg. A maximum patient weight per size should be obtained, since a band is not something to fit a patient against.

Yes, and particularly in bilateral fittings, where soft heel cushions on both sides can leave a user with a tendency to fall backwards and firmer cushions are indicated.

It determines which footwear the foot suits, so a user who wears shoes of differing heel heights needs that accounted for at fitting.

Through a foot adapter, with the attachment method and compatible adapters confirmed at quotation.
