The FORS™-15 Off-Loading Insole

The Durable and Adaptable Foot Off-Loading Solution, for damaged and vulnerable feet

Consistent Off-Loading & Cushioning

  • Durable memory resistant Poron® for consistent cushioning, crush resistance, and long life.
  • Highly stable off-loading zones; pre-cut plugs are torn out to create off-loading zones, but remain solidly in place when not disturbed. If you have ever experienced products with unstable and shifting pegs that produce inconsistent off-loading, you will welcome the durability and predictability of the FORS™-15 system!


Best in Class Materials

  • Total of 15mm thick Poron® padding, with 5 mm always present under the foot, even after plugs are removed. Unique fabric mid-layer prevents off-loaded areas from collapsing. Tough and abrasion resistant Alcantara® top covers minimize slip and sheer, absorb perspiration, are non-allergenic and bacteria resistant.
  • Multilayered Poron® provides softness and support where needed: softer “slow rebound” Poron® adjacent to the foot, and denser Poron® below for support.


Uniquely adaptable:

  • The FORS™-15 insole can be trimmed to any desired shape or size.


Easy Care:

  • To completely clean and disinfect, soak the FORS™-15 insole in 10% chlorine bleach solution for 10 minutes and lightly scrub as needed, then thoroughly rinse and air dry.

FORS™-15 sizes are designed to correspond to industry standard surgical shoes and boots constructed with removable foam inserts. The FORS™-15 is designed for surgical shoes and therapeutic boots.


  • One of the most common complications of diabetes
  • Annual incidence 1% to 4% with lifetime risk of 15-25%
  • ~15% of diabetic foot ulcers result in lower extremity amputation
  • ~85% of lower limb amputations in patients with diabetes are proceeded by ulceration
  • Mortality rates following amputation of up to 40% at 1 year and 80% at 5 years
  • Peripheral neuropathy is a major contributing factor in diabetic foot ulcers
  • 30% – 40% recurrence within 1 year

What’s missing from the therapeutic Arsenal?

An inexpensive and effective “intermediate” off-loading approach

  • When restrictive devices contraindicated
  • Non-compliant patients
  • Small wounds
  • Transitional offloading shoe for after the wound is closed, but before ready for an extra-depth shoe

Why has the FORS insole worked where others have fallen short?

  • Patient comfort = compliance
  • No edge effects
  • No peg instability
  • Durability, doesn’t crush
  • Easily customized

Benefits of the FORS Device

  • Improve patient compliance
  • Reduce healing times
  • Reduce DFU recurrence rates
  • Reduce amputation and mortality rates
  • Reduce total cost of care

The Off-Loading insole FORS™-15 is a medical device for the treatment of plantar ulcers according to the EC Regulation 93/42. The insole incorporates 15mm Poron® construction with pre-cut plugs that can be removed to alter the thickness of the insole in targeted areas

How to use it

  • This product is intended for use only with post-surgical shoes and Walker.
  • The product should be sold and used only with a medical prescription or as suggested by a qualified health practitioner.
  • Before using, verify that the insole is equal to or larger in size than the foot-bed of the selected shoe (or boot) to avoid causing trauma to the foot.
  • The cushioning and off-loading capacity of the FORS-15 insole will vary depending on user’s size and weight, activity level, and on the number of plugs that are removed.

User Instruction

  1. How to mark the footprint:
    • Using Povidone-iodine (PVP-I) or similar colored/transferable marking material, trace directly on the plantar side of the foot around the area(s) that are to be off-loaded. The area must be protected with a proper medication.
    • Using the special adhesive paper align the heel perfectly to the signed area and apply adequate pressure to transfer (PVP-I) marking material, to obtain the correct footprint. In alternative wide strip of removable tape can be used.


  2. How to create the off-loading area:
    • If the shoe comes with a removable insole, remove it. (The FORS-15 will replace it.)
    • If necessary, trim the FORS-15 to fit the foot-bed of the shoe. (If a removable insole was present, it can be used as a template for trimming the FORS-15.)
    • Place the adhesive paper on the insole with Alcantara side facing up
    • To create the off-loading zone(s), tear out the Poron plugs that are located on the bottom of the insole and that are underneath the transferred markings. The plugs can generally be torn out with one’s fingers, but grasping tools can also be used


  3. Place the insole in the shoe with Alcantara fabric facing upwards. The shoe is now ready for use.

To Clean and Disinfect the FORS-15 Insole

  1. Remove the FORS-15 insole from the shoe.
  2. Completely cover and soak the FORS-15 insole in 10% chlorine bleach solution for 10 minutes (9 parts water to 1 part bleach). Lightly scrub the Alcantara top cover as needed to remove stains during the soaking process.
  3. Thoroughly rinse the FORS-15 insole in warm tap water for 60 seconds.
  4. Towel dry to remove excess water, and then air dry until dry to the touch. Dry time will vary based on temperature and humidity. Do not put the product next to the fire or sources of excessive heating.
