Skin Problems with Boots and Bar: What's Normal, What's Not
If your baby is wearing boots and bar (a foot abduction brace) as part of their clubfoot or talipes treatment, you've probably already inspected their feet more times than you can count. Every red mark triggers a wave of anxiety. Every tiny blister sends you spiralling. And the sweaty feet — is that normal?
Take a breath. Most skin issues with boots and bar are minor, manageable, and don't mean anything is seriously wrong. But some do need attention. This guide helps you tell the difference and gives you practical solutions for the most common problems.
Red Marks: The Most Common Concern
What's Normal
Red marks on the feet after removing the boots are completely normal. Any shoe, sandal, or boot leaves pressure marks on skin — your baby's feet are no different. The key question isn't whether there are red marks, but how quickly they fade.
- Normal red marks: Fade within 15-20 minutes of boot removal. Skin returns to normal colour. No broken skin.
- Concerning red marks: Still visible after 30+ minutes. Deep indentations in the skin. Broken skin or blistering. Located over bony prominences (heel, ankle bone, toe joints).
Where Red Marks Typically Appear
- Heel: The most common location. The heel strap applies the most pressure to keep the foot seated in the boot. Some redness here is expected.
- Top of the foot: Where the tongue and straps cross the foot. Usually cosmetic and fades quickly.
- Side of the ankle: The lateral malleolus (bony bump on the outside of the ankle) is a common pressure point.
- Base of the toes: Particularly the big toe and little toe, which can rub against the sides of the boot.
Reducing Red Marks
- Check the sock situation. Socks should be smooth with no wrinkles. A wrinkle under a strap creates a pressure point. Pull socks taut before closing the boots.
- Use the right socks. Thin, smooth cotton or bamboo socks work best. Avoid thick, textured socks. Many parents swear by AFO (Ankle-Foot Orthosis) socks — these are specifically designed for braces. Brands like SmartKnit and Seamless Sensitivity sell them. Available on Amazon or through NHS orthotics departments.
- Don't overtighten the straps. The boots need to be snug but not vice-tight. You should be able to slide a finger between the strap and the skin (just). If you can't, they're too tight.
- Talk to your orthotist. If red marks are persistent in one specific area, your orthotist can adjust the boot — adding padding, changing the tongue position, or modifying the strap placement.
Blisters: When Friction Becomes a Problem
Why Blisters Happen
Blisters form when there's repeated friction between the boot and the skin, usually combined with moisture (sweat). They're more common in:
- Hot weather or overheated rooms
- The first few weeks of brace wear (before the skin has toughened up)
- After a growth spurt when the boots are becoming tight
- When socks are damp from sweat
How to Manage Blisters
- Don't pop the blister. An intact blister is nature's own bandage. The fluid underneath protects the new skin forming beneath.
- If the blister has already burst: Clean gently with cooled boiled water or saline. Apply a thin layer of antiseptic cream (Savlon or similar). Cover with a non-stick dressing (Melolin or similar) under the sock.
- Contact your orthotist. A blister means something is rubbing that shouldn't be. You may need a boot adjustment, different socks, or a padding modification.
- You can continue wearing the boots over a blister (with appropriate dressing) unless your orthotist advises otherwise. Stopping brace wear is worse for your baby's clubfoot treatment than a minor blister.
Preventing Blisters
- Change socks frequently. Damp socks = increased friction. Have 5-6 pairs so you always have clean, dry ones ready.
- Apply a barrier product. A thin layer of Vaseline or Bepanthen on friction-prone areas (heel, ankle bones) before putting on socks can reduce rubbing.
- Ensure correct boot size. Boots that are too small cause pressure; boots that are too big cause sliding and friction. Your orthotist should check sizing every 3-4 months.
- Moleskin patches. These adhesive padded patches (available from pharmacies) can be placed directly on the skin or inside the boot at friction points.
Sweaty Feet: Managing Moisture
Babies' feet sweat in boots. This is normal but can lead to maceration (softening of the skin from moisture), which makes blisters and irritation more likely.
Solutions for Sweaty Feet
- Cotton or bamboo socks wick moisture better than synthetic materials. Avoid nylon or polyester.
- Change socks mid-day if they're damp. A quick sock change during a feed takes 30 seconds.
- Remove boots during the "off" period and let feet air-dry completely before reapplying.
- Talcum powder: A light dusting of talc-free baby powder on the feet before socking can help absorb moisture. Some parents use cornflour as a natural alternative.
- Dry the boots out. During the off period, stuff the boots with newspaper or leave them open to air. Don't put them on a radiator — this can crack the leather.
Skin Breakdown and Pressure Sores
A pressure sore is more serious than a blister. It's an area where constant pressure has damaged the skin, sometimes through to deeper layers. Signs include:
- An area of red or purple skin that doesn't blanch (turn white) when you press it
- Broken skin with clear or yellowish fluid
- An area that feels hard or thickened
- Your baby being unusually fussy about having the boots put on (more than normal settling fuss)
If you suspect a pressure sore, contact your orthopaedic team or orthotist promptly. Don't try to manage it yourself. The boot likely needs modification, and the sore may need medical attention. You may be advised to have a short break from the brace while the skin heals — your consultant will balance skin healing against clubfoot treatment needs.
The Heel Issue: Keeping the Heel Down
The single most important thing about boot fit is that the heel sits fully down in the boot. If the heel lifts up, the boot isn't doing its job, and the friction of the heel moving up and down is the primary cause of heel blisters.
How to Check Heel Position
- With the boot on, press down on the sole of the boot where the heel is.
- You should feel the heel bone firmly seated against the back of the boot.
- If you feel a gap, the heel has lifted.
If the Heel Keeps Lifting
- Re-do the straps. Often, tightening the heel strap first (before the mid-foot and forefoot straps) keeps the heel seated better.
- Check with your orthotist about strap technique — they can demonstrate the correct order and tension.
- The boots may need adjusting or replacing if they've been outgrown.
- Some bars (like the Dobbs bar) have a plantar flexion feature that helps keep the heel down. Ask your orthotist if this applies to your brace.
Seasonal Considerations
Summer / Hot Weather
- Increased sweating = more skin problems. Change socks more often.
- Keep the room cool at night (16-20°C is ideal for baby sleep anyway).
- Use a lightweight sleep sack (0.5 TOG) or just a vest.
- Don't add extra layers to cover the boots — overheating is a bigger risk than cold feet.
Winter / Cold Weather
- The boots actually keep feet reasonably warm. You usually don't need extra socks.
- For outdoor trips, a fleece pram suit over the boots works well.
- Don't use thick socks to keep feet warm — this changes the boot fit and can cause more problems.
Products That Help
- AFO socks (SmartKnit / Seamless Sensitivity): Seamless, moisture-wicking socks specifically designed for braces. Around £5-8 per pair.
- Vaseline / Bepanthen: Barrier protection for friction points. Apply before socking.
- E45 / Aveeno / Diprobase: For general moisturising during the off period. Keep skin supple and healthy.
- Moleskin patches: Self-adhesive padding for persistent pressure points.
- Melolin non-stick dressings: For covering open blisters under socks.
- Sudocrem: Good for minor skin irritation around the cast/boot edges.
When to Contact Your Clinic
Contact your orthotist or orthopaedic clinic if:
- Red marks don't fade within 30 minutes of boot removal
- You see blisters forming — especially recurrent blisters in the same spot
- There's any broken skin, bleeding, or weeping
- Toes appear swollen, blue, white, or very cold
- Your baby seems in pain (not just frustrated) when boots are applied
- You notice the boots are leaving deep indentations that don't resolve
- The skin smells unusual or looks infected (redness spreading, warmth, pus)
Don't feel like you're wasting their time. Boot-related skin problems are one of the most common reasons parents contact their clinic, and your team would much rather hear from you early than deal with a serious pressure sore later.
Frequently Asked Questions
My baby has red marks every time the boots come off. Is this normal?
Yes, mild red marks that fade within 15-20 minutes are completely normal. Any boot or shoe leaves marks on skin. Only worry if the marks persist beyond 30 minutes, the skin is broken, or the marks are deep and indented.
Can I put cream inside the boots?
Don't put cream directly inside the boots — it can deteriorate the leather and create a slippery surface. Apply moisturiser to the feet, let it absorb fully (5-10 minutes), then put on socks and boots. Barrier products like Vaseline should go on the skin, not in the boot.
How often should boot size be checked?
Your orthotist should check boot size at every clinic appointment, typically every 3-4 months. Between appointments, watch for signs the boots are getting tight: increased redness, difficulty getting the foot in, toes right at the end of the boot, or your baby seeming more uncomfortable than usual.
My baby's feet smell terrible when the boots come off. Is this normal?
Sweaty feet in leather boots will smell — that's normal. Wash feet during the off period, change socks regularly, and air the boots out. If the smell is accompanied by discharge, redness, or broken skin, this could indicate a fungal or bacterial infection, and you should see your GP.
Can I put insoles in the boots?
Never modify the boots yourself. If you think insoles or additional padding would help, speak to your orthotist. They can make professional modifications that maintain the correct biomechanical positioning.

What if my baby pulls their foot out of the boot?
A foot slipping out of the boot is a fitting issue, not a skin issue. Contact your orthotist — the boots may need adjusting, the strap technique may need refining, or the boots may have been outgrown. A foot that repeatedly comes out is not getting the treatment it needs.
