That Sharp Pain Under Your Heel? Here’s What’s Going On.

You swing your legs out of bed, put your foot down, and the bottom of your heel lights up. Then it comes back after you’ve been sitting for a while.

That’s your plantar fascia. It’s a thick band of tissue that runs along the sole of your foot from your heel to your toes. Every time you take a step, it absorbs force and releases it. When it gets irritated, usually from too much load without enough strength to support it, it lets you know about it. Healthdirect’s guide to heel pain and the NHS overview of plantar fasciitis are worth reading if you want more background on what’s happening in the tissue.

Why Does It Stick Around

The frustrating thing about plantar fasciitis is that rest alone doesn’t fix it. You rest, it feels great, you walk more, it flares up again. That cycle can go on for months.

The reason is that rest doesn’t actually address the problem. Your plantar fascia is telling you it can’t handle the load you’re asking it to carry. Physiopedia’s breakdown of plantar fasciitis explains the loading mechanics well if you want to go deeper. Three things usually contribute: weak foot muscles, tight or weak calves, and sudden changes in activity like new shoes, more walking on holidays, or ramping up running too fast.

Start With Your Feet

Your feet have small, intrinsic muscles that support your arch and control how force travels through your foot. Most people never train them directly.

Short Foot Exercise

1. Stand barefoot with your toes spread wide on the floor.
2. Draw the ball of your foot back toward your heel, like you’re trying to shorten the sole of your foot.
3. Let your arch lift. Keep your toes long, not gripping.
4. Hold for five seconds, then relax.
5. Repeat ten times.

These muscles are small, and most people haven’t asked them to work like this before. Give it two weeks of daily practice, and you’ll start to feel a difference in how your foot handles load.

Toe Control

Place your foot flat on the floor. Lift your big toe while keeping the other four down. Then reverse it: press your big toe down and lift the other four.. If you can’t do it yet, that’s useful information. It tells you the coordination in your foot has room to improve. Practice both of these barefoot at home. Before class, while the kettle boils, wherever you can fit them in.

Build Your Calves (Two to Three Times a Week)

Your calves do a huge amount of work every time you walk, climb stairs, or push off during movement. If they’re not strong enough, your plantar fascia picks up the slack. That’s often what tips it over the edge.

Week One to Two: Double-leg heel raises. Stand near a wall for balance. Rise up onto the balls of both feet, hold at the top for two seconds, then lower slowly over three seconds. Three sets of twelve.

Week Three to Four: progress to Single-Leg Heel Raises. Three sets of eight on each side. Start with whatever number feels controlled and build from there. There’s no rush.

Week Five Onward: add load. Hold a weight, wear a backpack, whatever you have. The goal is progressive overload. Your calves need to get stronger than the demands of your daily life, not just match them.

Do these two to three times a week, not every day. Your calves need recovery time between sessions to actually adapt.

Move Smarter, Not Less

You don’t need to stop walking or skip your classes. But pay attention to a couple of things while your heel is grumpy.

Shorten Your Stride a Little. Heavy heel striking with a long step puts more load through the plantar fascia. Shorter, lighter steps distribute the force well.

Check Your Shoes. Worn-out soles or completely flat shoes can aggravate things during a flare-up. You don’t need anything fancy. Just something with a bit of support while you’re building strength. And if you notice it’s worse after a particular activity, don’t push through it. Back off, let it settle, then return gradually. Consistency over intensity.

When to See a Physio

If you’ve been doing the foot and calf work for three to four weeks and it’s not improving, or if the pain is sharp enough that it’s changing how you walk, get it assessed. Physiotherapy can look at your gait, test your strength, and figure out what’s driving it for you specifically. Early intervention makes all the difference. The longer plantar fasciitis goes on, the longer it takes to resolve. If it’s been bothering you, don’t wait.

In the meantime, studio sessions give an instructor the chance to incorporate foot and calf work directly into your sessions.

You can also build consistency through in-person Pilates classes or online Pilates classes if you prefer to work from home. Check the pricing page to find the right option for you.

The Short Version

We view heel pain as a capacity and loading challenge. Train your feet. Build your calves. Be consistent. Most people see meaningful improvement within six to eight weeks.

If you want your teacher to incorporate foot and calf work into your sessions, simply ask your teacher. We incorporate this into our sessions regularly.
