Coming Out of the Boot after an Achilles Tendon Rupture
Coming out of the boot is one of the most significant milestones in Achilles Tendon Rupture (ATR) recovery and one of the most misunderstood.
Your tendon is not "healed" at this point; it is structurally sound enough to begin progressive loading. The calf muscle will have wasted severely, and your ankle will feel stiff and weak.
The goal of the next 6 to 8 weeks is to restore normal walking mechanics, begin rebuilding the calf through double-leg calf raises, and progressively advance to the single-leg calf raise the single most important exercise in your entire rehabilitation.
At Wimbledon Physiotherapy Clinic, we use force plates to measure exactly how much weight you are bearing through each leg at every stage, removing all guesswork and allowing us to progress you safely and objectively.
Why coming out the boot feels so alarming?
After 8 to 10 weeks in a boot, the moment you take it off and look at your leg, the shock is real. The injured calf will look dramatically smaller than the other side often 2 to 4 centimetres smaller in circumference.
Your ankle will feel stiff, your heel will feel tight, and your first few steps without the boot will feel deeply unfamiliar.
This is entirely normal, and it does not mean something has gone wrong. It means your body has been doing exactly what it is designed to do: protecting the healing tendon by reducing load. Now, your job and your physiotherapist's job is to systematically reintroduce that load in a controlled, progressive way. This will start with a wedge in your shoe and back on the elbow crutches
The two biggest risks at this stage are:
-
Loading too much, too fast which can stress the immature healing tissue and cause the healing tendon to elongate which later on can cause problems with returning to sport.
-
Loading too little, too cautiously which prolongs muscle atrophy and delays your recovery by weeks or months.
The only way to navigate between these two risks accurately is with objective measurement.
How we use force plates to guide your progression
At The Wimbledon Clinic, we use dual force plates from the moment you transition out of the boot. Force plates are precision instruments on the floor that measure the exact amount of body weight being transmitted through each foot in real time.
This technology transforms what is normally a guesswork process into a data-driven one.
Stage 1: Baseline weight-bearing Assessment
The first thing we do when you come out of the boot is stand you on the force plates in a normal standing position. On our iPad we will immediately be shown how much of your weight is distributed between your two feet.
Most patients, even those who feel they are standing normally, are subconsciously offloading their injured leg. We routinely see patients bearing only 35% to 40% of their weight through the injured side, with 60% to 65% going through the healthy leg.
This asymmetry matters because it reveals a compensation pattern that, if left uncorrected, will persist into walking, jogging, and eventually sport increasing the risk of injury to the uninjured leg and slowing the stimulus for the injured calf to rebuild.
Our target at this initial stage is to achieve 50/50 weight distribution in standing before we progress to any dynamic exercises.
Stage 2: Double Leg Calf Raise
Once you are bearing weight symmetrically in standing, we introduce the double-leg calf raise. This is the foundational exercise for rebuilding the Achilles and calf complex.
However, performing a double leg calf raise without force plate feedback tells you very little. If you are doing 10 double-leg calf raises but subconsciously pushing 70% of the effort through your healthy leg, you are essentially doing single-leg calf raises on your good side and getting almost no stimulus to the injured one.
The force plates solve this problem instantly. As you rise onto your toes, the screen shows us the load split in real time. We can see if you are pushing equally, or if you are cheating to the healthy side.
Stage 3: Stagged Single leg calf raises
Once you are able to perform 50/50 double leg calf raises we perform with a step so we can offload your non injured side so we can gradually increase the weight through your injured side working towards the target for this stage of the Single leg calf raise.
Until you hit these benchmarks, you do not progress. The force plates make this decision objective, not subjective.
Stage 4: The single-leg calf raises
This is the most important exercise and test in the entire first part of the rehabilitation process. It is the benchmark that determines that you are able to progress to taking greater than body weight through your limb so you can run to activities like running in the future.
A full, strict single-leg calf raise requires the calf to generate enough force to lift your entire body weight through a full range of motion, with control. When you first attempt this, it will likely feel impossible. Your injured calf will shake, your range of motion will be limited, and you may only manage two or three partial repetitions.
The Psychological side of losing the boot
It is worth acknowledging that coming out of the boot is not just a physical transition. For many patients, the boot provides a sense of security a visible signal to the world that you are injured, and a physical reminder to yourself not to overdo it.
Removing the boot can feel exposing. The fear of stepping awkwardly and damaging the healing tendon is very real. This is entirely rational, and it is something we address directly in clinic.
By showing you your force plate data by proving to you that your tendon is handling the load safely we replace that fear with evidence. You are not guessing whether your leg can cope. You can see it on the screen.
FAQ
My ankle is incredibly stiff when I first come out of the boot. Is this normal?
Yes, completely. The boot holds your ankle in a slightly plantarflexed (toes-down) position for weeks. The calf and the Achilles will feel tight when you first try to flex the ankle. Do not stretch the Achilles over time as you start walking this will gradually get better. We want the Achilles tight. The physio can perform some technique to help manage the tightness if needs at a later stage.
I can feel a lump or thickening at the back of my heel. Is that the tendon?
Yes. It is very common to feel a palpable thickening at the repair site. This is the healing scar tissue and new collagen. It typically softens and becomes less prominent but can take up to a year and beyond as the tissue remodels.
How long will it take to get from the boot to doing a single-leg calf raise?
For most patients, the transition from boot removal to achieving a first full single-leg calf raise takes between 6 and 10 weeks.
Should I use a heel raise in my shoe when I come out of the boot?
Yes, initially. We recommend a 1 to 2cm heel raise in your regular shoe for at least the first 2 to 4 weeks until the calf can hold some of your body weight out of the boot, we will guide you when it’s time to remove.
