Must have
An absolute must have if you’ve ruptured your Achilles and want to be able to sleep without wearing the boot in bed or in the shower. Fits great, is comfortable and does what it needs to, pricey but worth it

Worth it!
If you've ruptured your Achilles tendon... Commiserations! It's not fun. And it's not a quick recovery. You will have been given a Controlled Ankle Movement (CAM) boot and, after wearing it all day, there's no respite at night. Like me, you might find that sleeping in the boot is even harder than walking in it. It's hot. Things you don't notice during the day suddenly become impossible to ignore: a bit of pressure here, a bit of rubbing there. And you can't sleep. This is exactly what the night splint is designed to solve. And it works. As others have noted, the splint is not cheap, but it's a niche product, made by a small company, and there's little scope for economies of scale. You're paying for the expertise that went into its design too. In my view, it's worth every penny. It took me a bit of fiddling around making minor adjustments to the position and tightness of the straps to get it comfortable. It's a case of balancing security and comfort. I prioritised security and, the first night, I had tightened the strap that goes under the foot a little too much and, as a result, the splint was pressing on the top of my foot too much for a whole night's comfort. I was also concerned that the strap at the heel might cause problems, but it hasn't. In the end, I've found that I'm actually having the heel strap a little tighter than the calf and foot straps and that's got the balance between security and comfort about right. I've still found that a cotton wool make-up pad, half under the splint, at the edge nearest my small, outer toes helps: everyone's feet are different and I found that was a bit of a pressure point. However, it's worth the effort: I've been able to sleep well and the splint has remained secure. The recovery of my Achilles tendon remains on track too. In summary, then, this has been a very worthwhile purchase. It's a good example of a small company that's identified a problem and provided a solution. (Note: the Thetis website is also an excellent source of information about Achilles tendon injuries and recovery.) I would also suggest searching for the Evenup Shoe Balancer on Amazon: another helpful product but one that makes walking with a CAM boot a bit easier.

It’s okay ….. works , but not the best construction or design .
This is a bit of a godsend , the big boot is uncomfortable to wear in bed at night. However …… the price is VERY steep for what is essentially a shin guard with Velcro. I bought the large size but it’s very narrow and the curve doesn’t sit on my shin well , also the finish on the Velcro strap is melted with sharp edges that scratched and cut my skin in the night ( not great to have skin damage with ruptured Achilles and in the boot ) and the front digs into my foot. I’ve had to make felt pads to stop the discomfort .For the money , it could be a lot better designed . It does the job , with a bit of help from the user.

Definitely recommend
I would definitely recommend this for anyone with a ruptured achilles. I was told i could go to bed without my surgical boot on but I found it difficult to sleep as was worrying about position of ankle. This splint made all the difference and I could sleep knowing I couldn't do any more damage

THIS PRODUCT IS GROSSLY OVERPRICED AND DOES NOT WORK.
THIS PRODUCT IS GROSSLY OVERPRICED AND DOES NOT WORK. ON MY CONSULTANT'S RECOMMENDATION I BOUGHT THE SPLINT TO WEAR IN BED AT NIGHT INSTEAD OF A SURGICAL BOOT. FROM DAY 1 IT DID NOT LIE FLAT ON MY LEG AS PER THE ILLUSTRATION AND KEPT TWISTING ROUND . BECAUSE OF THIS IT DID NOT HOLD MY ANKLE IN THE CORRECT POSITION AND THUS MY RUPTURED TENDON DID NOT HEAL. I WASTED 4 WEEKS UNTIL I SAW THE CONSULTANT AGAIN AND HE CONFIRMED THAT THE SPLINT WAS USELESS.

Pictures no longer match reality
Pictures show a splint with considerable padding, the one I received has fabric edging with sharpe edges, and almost no padding at all, it’s marginally better than the boot, but given the cost I can’t help but feel a little robbed, the main discomfort is effectively having a plastic shell strapped to your shin, and with the padding that is missing this would be less of an issue. I’m going to return it because the reality of what it is now vs the images is too different.

Good product for early post-surgery weeks
I ordered this splint and arrived after a few days, but i was already 5 wks after surgery. Already wearing an Ossur Rebound Air Walker, with 5 wedges. I believe the splint would have been great for earlier stages; right now i cannot use it because the position of my foot is not at maximum equine. Therefore I would advise for usage very early, before starting to take out wedges. Otherwise, great product, good quality, balanced price (no other comparable option).

Excellent part of Achilles rupture rehab
After rupturing my Achilles I have worn this in bed every night for almost 10 weeks with my leg raised up on a pillow. I could sleep well and more importantly the splint stayed on and didn’t move. The Velcro straps fitted well and it’s only now - almost 10 weeks later they are loosening slightly. My consultant has said I can sleep without the splint after 10 weeks. During the day I’m in a vacoped boot and use crutches. I was not keen to sleep in the boot even though the doctor and physio said many people do.

Retter des erholsamen Schlafes
Dank Achillessehnenriss muss ich mindestens 6 Wochen, Tag und eigentlich auch Nacht, eine Orthese/Walker/Vacoped tragen . Als Seitenschläfer konnte ich mit dem Klotz so gut wie gar nicht schlafen . Diese Schiene ist nachts Gold wert !

COMODO E SALVA-SONNO
Una vera benedizione. Dormire con lo stivale Walker è un incubo. Incredibile che nessun altro produca un tutore simile. Mi ha letteralmente salvato il sonno. Solo bisogna trovare il giusto compromesso tra tensione delle fasce elastiche, per la sicurezza che non si sposti, e la comodità per poter dormire. Io ho dormito molto bene già la prima notte, mi ha dato un senso di sicurezza che ,senza lo stivale, non avrei potuto avere. È molto leggero, e finalmente posso dormire sotto le lenzuola, e non con la gamba fuori. Direi un must per il post-operatorio del tendine d'Achille.

Hård
För hård. Man får ont ovanför tårna. Borde vara lite mer vinklad. Även lite bredare.

Finally Relief
How to start my review. I am on day 25 Achilles rupture and the first two weeks in the surgical splint i slept fine then they removed stitches and put me in a ten pound prison called a Breg air boot. Don’t get me wrong the boot is fantastic for weight baring walks but hell for sleeping. I describe it like putting my foot to knee in a camp fire the leg is hot sweaty pins and needles start firing everywhere foot out of boot no issues except you could re tear the tendon with a sneeze then this product it’s light still a bit hot on the top of the foot and lower shin but it holds in place nicely and protects the tendon from the sneeze or twitch or waking up from a dream where you’re falling. Is it expensive as some say based on materials yes but i think its priced right. Its very specific for Achilles tendon rupture and all the other splints are for plantar fasciitis not for keeping the Achilles tendon safe while healing resting and sleeping.
