Can Insoles Help Reduce Pressure Under the Foot?

Insoles can change how pressure is distributed under the foot and may add cushioning or support, but the right design depends on your foot shape, footwear and diabetic foot risk.

If you have reduced sensation, previous ulceration, significant deformity or an active wound, pressure relief should be directed by a specialist foot-care service rather than managed with a generic retail insole.

How can an insole change pressure?

An insole can alter the contact between the foot and shoe. Depending on its shape and material, it may spread load across a wider area, cushion the foot or accommodate a particular region.

Does softer always mean better?

No. Very soft materials can feel comfortable but may compress quickly or fail to control pressure in the way a particular foot requires. Pressure management is about the whole foot, shoe and insole combination rather than simply choosing the softest material.

Can an insole make footwear tighter?

Yes. Any insole takes up space. If the shoe lacks enough depth, adding an insole can increase pressure around the toes, forefoot or upper.

Can an insole treat a diabetic foot ulcer?

An active ulcer needs professional treatment. Specialist offloading devices and orthoses can be part of ulcer management, but they should be selected and monitored by the relevant foot-care team.

When might specialist orthoses be needed?

NICE recommends that people at moderate or high risk are assessed by a foot protection service, including consideration of biomechanical status, specialist footwear and orthoses.

How should you check an insole?

Make sure it lies flat, does not curl or crease, and does not create an obvious ridge or pressure point. Inspect the skin after wear, particularly if sensation is reduced.

What if an insole causes redness?

Stop using it and seek advice if redness persists, especially where sensation is impaired or you are at increased diabetic foot risk.
