Can't Sleep with a Torn Achilles?
Sleep problems are the #1 complaint during Achilles recovery - you're not alone
of patients struggle with sleep during boot phase
- • The boot is heavy, hot, and uncomfortable
- • You can't find a comfortable sleeping position
- • You're exhausted but can't get quality rest
Why Sleep Matters for Achilles Healing
Quality sleep is critical for tissue repair and recovery
"Sleeping in a walking boot is one of the hardest parts of recovery. Around 80% of patients struggle with sleep during this phase. The boot is heavy, rigid, hot, and feels like sleeping with a brick strapped to your leg."
sleep difficulties are frequently reported during boot phase
walking boots are bulky and uncomfortable for sleeping
protection needed - even while sleeping
Tissue Repair
During deep sleep, your body releases growth hormone which supports tissue healing and recovery.
Pain Management
Quality sleep helps your body manage pain more effectively and supports overall healing.
Mental Health
Poor sleep can increase pain perception and affect mood. Good sleep helps you cope better with recovery.
Energy & Recovery
Rest is essential for healing. Quality sleep helps your body dedicate resources to recovery.
Critical Safety Warning
Removing your boot while sleeping is NOT safe and can cause serious damage. During the boot phase, you need protection 24/7 to keep the tendon ends together. Sleeping without protection is one of the most common causes of re-rupture or tendon elongation.
The Night Splint Solution
A night splint (like the Thetis splint) is a lightweight device that keeps your foot in the correct angle while being much more comfortable than the full boot. It's specifically designed for sleeping and washing.
- Much lighter than walking boot (hundreds of grams vs 1-2kg)
- Open design allows foot to breathe
- Maintains safe plantarflexion position
- Usually allowed after week 2-3 (check with clinician)
- Also allows foot washing
Sleep Tips for Boot Phase
- Sleep on your back with leg elevated on pillows
- Support your calf, not just your foot
- Keep the room cool - boots trap heat
- Use light bedding to prevent overheating
- Keep crutches by the bed with a nightlight
- Empty your bladder before bed to minimize trips

What Patients Say About Sleep
Total game changer for sleeping while recovering!
Finally got the restful sleep I needed. The cast and heavy dirty boot made sleep tough. If you're recovering from an achilles rupture buy this immediately.
Perfect splint for achilles injury recovery
It literally takes a few secs to put on and remove. Its comfortable as well. Highly recommend.
Life Saver!
This worked great and kept me from having to wear my big clunky walking boot to bed! So glad I found this. I couldn't sleep with that walking boot at night!! Great product.
Eine absolute Erleichterung!
Nach der OP an der Achillessehne war diese Schiene eine Erleichterung in der Nacht! Würde ich auf alle Fälle empfehlen wenn man wieder durchschlafen möchte!
Superb
Really useful after my dreadful Achilles tendon tear when I didn't want to wear the boot in bed!
Night time saviour
This is a saviour for night time wearing. So much easier than the big boot. Five weeks down and another five or six to go. Would have struggled with the full boot.
Peace of mind for Achilles injuries
A great alternative to wearing the walking boot to bed, without worrying about inadvertently straightening or knocking your foot.
Wonderful device and splendid service
Brilliant device. Arrived the day after it was ordered. Delighted in all respects.
