Slimflex Simple 3/4 Length Insoles

Highly versatile 3/4 Length medium density (50 shore) EVA insoles


Slimflex Simple 3/4 Length Insoles are a cost-effective, fully customisable foot orthotic. The device can be worn alone to provide general control or can be adapted by a clinician into a semi-bespoke device. 

Slimflex Simple 3/4 Length Insoles includes the following features:

1st met cut out – this provides a raised mechanism, reducing the pressure on the first Metatarsophalangeal Joint (MPJ) and easing tension in the plantar fascia area.

  • Metatarsal raise - supports the metatarsal area and redistributes weight away from the ball of the foot.
  • Deep heel cup - supporting the heel reduces pressure by redistributing the body’s weight over a greater surface area on the sole of the foot, while stabilising the foot to provide greater control and support.
  • Medial flange - increases control of the medial aspect of the rearfoot. This provides correction, stabilisation and gait training by increasing arch support.
  • Medial arch support and lateral control - improving misalignment of the foot. Aids in reducing pronation and improving sagittal plane control.



Due to the level of customisation that is achievable with the Slimflex Simple 3/4 Length Insoles, the treatment options with this device are endless. Slimflex Simple 3/4 Length Insoles offer an effective and speedy treatment to biomechanical pathologies.

Customisation options for the Slimflex Simple 3/4 Length Insoles include:

  • Heat mouldable and grindable, the Slimflex Simple allows for quick modification and patient customisation.
  • Simple medial and lateral posts - forefoot and rear
  • Heel lift additions
  • Metatarsal raise/bar additions
  • Top-cover replacements
  • Arch and rearfoot reinforcements
  • Shape modification

Good value, good relief
Saturday, 22 September 2018  | 

A great insole for relieving plantar fasciitis, my husband suffers badly and was recommended these by our orthotics team at hospital as he wears them himself. They offer a great support for the heel and arch. Well worth the money.

Simplex arch supports
Monday, 18 April 2016  | 

Delighted with my purchase. They give real support where needed and help me get better use from shoes I had purchased with little arch support that now will not need to be discarded.
