What we are trying to change
In Sever's disease the growth plate at the back of the heel is being irritated by repeated pull from the Achilles and repeated impact from running and jumping. We cannot speed up the growth plate maturing. What we can do is make the calf stronger and more tolerant, reduce the spikes in impact, and take the sharp edges off with simple footwear changes.
Quick wins in week one
- Swap worn or flat shoes for cushioned trainers for training on hard surfaces.
- Limit time in studded boots, and change out of them straight after matches.
- Add a gel heel cup or small heel raise in both shoes during the irritable phase.
- Cut repeated sprinting and jumping volume by roughly half for two weeks, keeping the rest of sport in.
- Move some conditioning to bike or swim so fitness is maintained without heel impact.
Stage 1: isometrics and range
- Double leg heel raise hold at the top: 30 to 45 seconds, 4 sets, most days.
- Seated calf isometric pushing into a wall or band if standing is too sore.
- Calf stretch, knee straight and knee bent versions, short holds, daily.
- Toe and foot work: toe curls, arch lifts, to build the small foot muscles.
Stage 2: build calf strength
| Exercise | Sets and reps | Progression |
|---|---|---|
| Double leg heel raise | 3 x 15 slow | Add a backpack, then move to single leg |
| Single leg heel raise off a step | 3 x 12 | Full range down, pause at the top |
| Bent knee heel raise | 3 x 12 | Loads the soleus, often the weak link in runners |
| Split squat and step-down | 3 x 8 each leg | Whole leg strength, not just the calf |
| Hamstring bridge | 3 x 10 | Supports running mechanics |
Two to three sessions per week, four to six weeks.
Stage 3: reintroduce impact
Step 1
Skipping and pogo hops
Low height, on a forgiving surface, small volumes.
Step 2
Single leg hops
Hop and stick, then continuous, quality first.
Step 3
Running
Build distance at easy pace before adding speed.
Step 4
Sprint and cut
Acceleration and change of direction at drill intensity first.
Step 5
Full sport
Part training, full training, then match minutes across two to three weeks.
Add one step at a time, keeping the next morning as your guide.
How long it takes and when to get help
Most young athletes notice a real difference within four to six weeks of consistent calf work and load adjustment, and are back to a normal week inside a couple of months. Symptoms can come and go until the growth plate fuses, so keeping the calf strength work in the weekly routine is worth it well after the pain settles.
Get an assessment if there is a limp that is not settling, pain underneath rather than behind the heel, swelling or redness, night pain in one fixed spot, or no progress after six to eight weeks of doing the right things.
