Why the Brace Matters
After the casting phase of Ponseti treatment, your baby will transition to a foot abduction brace — commonly known as "boots and bar." This brace is arguably the most important part of the entire treatment, because it maintains the correction that the casts achieved. Without it, relapse is almost certain.
But not all braces are the same. Several different systems exist, and in the UK, what you're offered depends on your hospital trust and orthotist. Some parents get a choice; many don't. Understanding what's available — and the strengths and weaknesses of each — helps you have an informed conversation with your orthopaedic team.
The Main Options
Dobbs Bar (Dynamic Foot Abduction Brace)
The Dobbs bar was designed by Dr Matthew Dobbs at St. Louis Children's Hospital in the USA. It's arguably the most innovative design on the market and has become increasingly popular in the UK.
Key features:
- Independent leg movement: The Dobbs bar has a joint in the middle that allows each leg to flex independently (plantar flexion). This is the biggest difference from a standard rigid bar — babies can kick and bicycle their legs while keeping the feet in the correct abducted position.
- Pre-attached boots: The boots are permanently attached to the bar, which means no fiddling with connectors at bedtime.
- Lightweight aluminium: Lighter than the traditional Dennis Brown bar.
- Quick-release buckle: Easy to open and close with one hand.
Pros:
- Independent leg movement may improve sleep (babies can move more naturally)
- Lighter and easier to handle
- Research suggests comparable or improved compliance rates
- Less clanking noise because of the dynamic joint
Cons:
- More expensive than a basic Dennis Brown setup
- The boots are permanently attached — if one boot is outgrown or damaged, you may need a whole new assembly
- Not all NHS trusts supply them (though increasing numbers do)
- Some parents find the buckle system less intuitive than traditional straps
Parent verdict: "We had the Dobbs bar and it was a major improvement. Oscar could kick his legs independently, which helped with sleep enormously. The first night was still terrible, but he adjusted faster than friends whose babies had the rigid bar." — James, dad to Oscar
Dennis Brown Bar (Steenbeek Foot Abduction Brace)
The Dennis Brown bar is the traditional foot abduction brace that's been used for decades. It's the "classic" boots and bar setup and remains the most commonly prescribed brace in many NHS trusts.
Key features:
- Rigid connecting bar: A straight or slightly bent metal bar connecting two boots. No independent leg movement.
- Separate boots and bar: The boots clip or screw onto the bar, meaning boots can be changed independently if outgrown.
- Various boot brands: Can be used with different boot brands (Markell, Mitchell, or custom-made boots).
- Adjustable width: The bar width is set to match the baby's shoulder width.
Pros:
- Long track record — decades of evidence supporting its effectiveness
- Lower cost (relevant for NHS procurement)
- Boots can be replaced individually
- Simple design with few parts that can break
- Most orthotists are very familiar with fitting and adjusting it
Cons:
- Rigid bar restricts all leg movement — babies can only move both legs together
- Heavier than the Dobbs bar
- More noise — the metal bar clanks against cot sides, floors, and furniture
- Some studies suggest slightly lower compliance rates compared to dynamic braces (because sleep disruption may be greater)
Parent verdict: "The Dennis Brown is clunky, noisy, and I won't pretend the first few weeks were easy. But it worked. Lily's feet are perfectly corrected at age 4 and we have the Dennis Brown to thank." — Emma, mum to Lily
Mitchell Boots (Ponseti AFO)
Mitchell boots are a specific brand of boot often used with a Dennis Brown-style bar. They were designed specifically for the Ponseti method and are used in many UK centres.
Key features:
- Open-toe design allows monitoring of toe colour and temperature
- Heel cup design aims to keep the heel properly seated
- Available through Iowa Brace (the original) and various licensed manufacturers
Pros:
- Designed specifically for Ponseti maintenance
- Good heel control
- Open toes allow easy monitoring
Cons:
- Some parents find the buckle system fiddly
- Can be hard to keep the heel down with very active babies
- Open toes mean cold feet in winter (socks help but can bunch)
Markell Shoes
Markell makes straight-last shoes that are sometimes used with a Dennis Brown bar. They're more shoe-like in appearance than the Mitchell boot.
Key features:
- Lace-up design familiar to parents who've used regular shoes
- Available in various sizes
- Can feel more "normal" than specialised boots
Pros:
- Comfortable for some babies
- Laces allow a customised fit
Cons:
- Laces take longer to tie than buckles
- Less heel control than the Mitchell design
- Being phased out in favour of Mitchell-style boots in many centres
MD Orthopaedics Brace
MD Orthopaedics makes the "original" Ponseti AFO (foot abduction brace) — the one endorsed by the University of Iowa where Dr Ponseti developed his method.
Key features:
- Designed to Dr Ponseti's exact specifications
- ADM (Abduction-Dorsiflexion Mechanism) sandals that clip onto the bar
- Available in standard and dynamic (D-BAR) versions
Which Brace Is Best?
The honest answer: the best brace is the one your baby will actually wear. Research shows that all of these braces are effective at maintaining correction when worn as prescribed. The differences in compliance rates between brace types are small compared to the differences between families who maintain brace wear and those who don't.
If you have a choice, consider:
- Your baby's sleep: If sleep is a major concern, the Dobbs bar's independent leg movement may help.
- Your dexterity: If you struggle with fine motor tasks (especially at 3 AM), a simpler buckle system might be better than laces.
- Your budget: If you're buying privately (some NHS trusts don't supply the Dobbs bar), cost is a factor. Dobbs bars are typically £200-400, while Dennis Brown setups may be less.
- Your orthotist's expertise: A brace fitted and adjusted by someone who knows it well will work better than a "better" brace fitted by someone less familiar.
Can You Switch Braces?
Some families switch braces during treatment — often from a Dennis Brown to a Dobbs bar if sleep problems persist. This is generally possible and your orthotist can arrange it. However, every brace change requires a period of readjustment, so don't switch for minor niggles.
If you're struggling with your current brace, talk to your orthotist first. Often, a strap adjustment, different socks, or a fitting tweak solves the problem without needing to change the whole system.
Frequently Asked Questions
Does the NHS provide the Dobbs bar?
It varies by trust. An increasing number of NHS trusts now offer the Dobbs bar, but some still default to the Dennis Brown. Ask your orthotist what's available. If they don't supply it and you feel strongly, you may be able to purchase one privately and ask your orthotist to fit it.
Can I buy a brace myself?
Yes, but it must be fitted by a qualified orthotist. Don't buy a brace online and fit it yourself — incorrect fitting can cause skin problems, poor correction, and potentially harm. Buy through your orthopaedic team or a reputable orthotics supplier.
How long does each brace last?
Boots typically need replacing every 3-6 months as your baby's feet grow. The bar itself may last longer. Your orthotist will check sizing at each appointment and replace components as needed.
Is the Dobbs bar really better than the Dennis Brown?
Some studies suggest slightly better sleep outcomes and parental satisfaction with the Dobbs bar, but the correction rates are comparable. "Better" depends on your family's priorities. Both are excellent braces with decades of combined evidence.
What if my baby's foot keeps slipping out of the boot?
This is a fitting issue, not a brace-type issue. Contact your orthotist — they may need to adjust the straps, change the boot size, or modify the fitting technique. A foot that repeatedly slips out is not getting adequate treatment.

Are there newer braces coming to market?
Several companies are developing new designs, including 3D-printed custom braces and braces with app-based wear-time monitoring. These are still emerging technologies but may become more widely available in the coming years.
