Aspen / Promedics x Thetis Medical
The missing night-time product for boot-led Achilles recovery.
Thetis Medical is looking for the right boot-manufacturer partner to scale the Achilles night splint. Aspen / Promedics already has the boot channel; Thetis can help make them the default supplier for Achilles tendon rupture.
Achilles rupture · Aspen / Promedics
Promedics already has the boot. Thetis completes ATR care.
Promedics sells walker boots into the same pathway, including Airstep, FixStep, and Traverse. Thetis adds the missing night-time product that can help Aspen / Promedics become the default supplier for Achilles tendon rupture.
Day · immobilisation
Promedics walker boot pathway
Airstep, FixStep, and Traverse cover daytime immobilisation, weight-bearing, and clinic supply.

Achilles wedges
Promedics already sells wedges with the boot pathway to position the foot for ATR recovery - splint sales can be compared exactly to wedge sales.

Great product to use about five or six weeks into a ruptured Achilles injury instead of the heavy large clumsy dirty boot they pit you in. Keeps the foot in a great healing position and you get a good nights rest.

Verified purchasegute Alternative zur Orthese
Eine gute und leichte Alternative wenn man die schwere Orthese nicht im Bett tragen möchte. Leider drückt das Teil ziemlich auf den Vorderfuss, dadurch behält man zwangsläufig die richtige Fußstellung ( was wohl so gedacht ist). War sehr zufrieden.

Verified purchaseComfortable and fit great
Perfect for sleeping!! I have a very injured Achilles tendon and this makes sleeping much better. It’s comfortable and fit perfectly. Also stayed in place while sleeping. I felt like my ankle was supported better in this than the boot I have.

Surgeons say yes
Leading foot and ankle surgeons recommend the splint for night-time use - the problem the walking boot cannot solve.
-
“A game-changer in my practice. The splint's design prioritizes both comfort and functionality, enabling controlled, progressive recovery.”
Dr Robbie Ray
Foot and Ankle Surgeon
-
“When I tore my own Achilles tendon, the hardest part was wearing the hospital boot in bed. This splint is certain to improve the recovery experience for patients.”
Mr James Davis
Past President of the British Orthopaedic Foot and Ankle Society
-
“Makes complete sense to use something like this and I highly recommend this product. Comfort and usability all round.”
Mr Andy Roche
Foot and Ankle Surgeon
-
“Worth every penny as it stops the misery of trying to get good nights sleep in an uncomfortable boot!”
Mr Ian Gill
Foot and Ankle Surgeon
