Detailed Description

Tall Pneumatic Walking Boot for Ankle Sprains

This is a pneumatic walker boot, meaning air cells control the amount of support and compression it provides to an injured ankle or boot. The compression helps reduce swelling and pain, while the extra support is needed after injuries to this area of the body.

In some cases, you may need to use crutches to keep weight off the leg for a period of time. Afterward, a controlled ankle motion (CAM) walker can protect and support the injured tissues.

The high-top ankle injury boot can help with stable fractures to the foot or ankle, moderate to severe ankle sprains, and other soft tissue injuries to the lower leg and ankle. You can also use it after surgery to the ankle or foot following a period of immobilization. The orthopedic boot may even be a good choice after a major (grade III) tear of the calf muscle.

We are often asked what the difference between a low- and high-top CAM walking boosts is. Tall walker boots extend farther up the leg, providing additional protection and support to the leg and ankle. Short CAM boots allow greater motion of the lower leg and less support.

While a short walking boot may suffice for a sprained or stress fractured foot, you will likely need taller boots for ankle injuries that are severe or higher up the leg. If you’re on the hunt for a boot for a sprained foot or some other injury to this appendage, this short pneumatic CAM walker is a similar product that is worth checking out.

The air boot for sprained ankle care featured here has uprights that are reinforced with metal for additional support. This is what sets it apart from another tall ankle fracture stabilizing boot BraceAbility sells. The latter has a polymer plastic shell that is a bit lighter.

The metal uprights are also contoured to fit the calf, which makes the ankle injury boots more comfortable.

The bottom of this ankle walker boot is a rocker style, with a low-profile heel. This design promotes a more natural gait, which is also beneficial for healing as well as for avoiding back pain that can result from walking in an unnatural way. 

As you can see from the pictures, the bottom of the ankle immobilizer boot is ribbed, which gives you more traction when moving about.

The footbed of the ankle boot for sprain treatment t is wide, which leaves space for any swelling or bandaging. For this same reason, the toe area is open. The heel of the support is cushioned to absorb energy and lessen any jarring that might irritate the injury as you move from place to place.

The immobility boot has a plush foam liner that is soft against the skin and lightweight. Note that you should also wear a sock lining with this support to further minimize the risk of chafing.

There are five straps that secure the air cast for sprained ankles in place. Each is easy to apply and adjust thanks to their Velcro closures and buckle loops. The strap at the ankle even features extra padding for a more comfortable fit and added stability. 

How a Boot for Ankle Injury Can Help

Ankle injuries are incredibly common, both in athletics and in everyday life. A poor landing to a basketball rebound, rolling the ankle when stepping off a curb or a car accident can all tear, stretch or break the structures of the ankle. Ankle sprains are especially common; around 25,000 of them occur each day!

As is the case with most injuries, treatment will depend upon how badly your ankle is damaged. Most sprains can be treated without surgery. This will likely involve following the steps of RICE (rest, ice, compress and elevate the ankle).

For moderate to severe sprains, you may have to use crutches and a non-weight bearing walking boot for a few days or weeks. Eventually, you will be able to transition to weight bearing with the help of a CAM walking boot.

The air chambers of this particular ankle sprain walking boot allow you to adjust how much compression it applies. Compression boosts blood flow, which in turn can lower inflammation and speed healing. Plus it protects the ankle from further damage.

You may also need to undergo physical therapy to return strength, flexibility, range of motion and balance to the ankle. During therapy, you may want to wear some sort of ankle sprain brace to ward off reinjury.  For this, you might consider either a lace-up ankle stabilizer or a compression sleeve.

Unfortunately, surgery may be needed to repair some severe ankle sprains or recurrent ones that have overstretched the ligaments of the ankle. Afterward, you will need to wear a plaster splint, followed by a tall CAM boot/walker like this one.

When it comes to an ankle fracture, treatment will depend largely upon whether the ankle fracture is a stable or an unstable one. If the bones of the ankle have not shifted out of position and the ankle is stable despite the fracture, surgery may not be necessary.

In such cases, you will likely need to wear a cast, a medical ankle boot and/or a splint for four to eight weeks, during which time you will need to avoid or limit weight bearing by using crutches. Frequent use of ice and elevation can help reduce pain and swelling in the immediate aftermath of a break.

At some point, use of an ankle walking boot will be incorporated. After a period of immobility, your muscles will have shrunk and lost strength and flexibility. Therefore, you will need to work with a physical therapist to regain your previous level of function.

For an unstable fracture where the break is severe and/or the bones are out of alignment, surgery to fix the bones in place as they heal will be necessary. This will extend your recovery time, but many of the steps of treatment after surgery are pretty similar to what you’d expect after non-surgical treatment, including use of a foot immobilizer boot.

Another instance where you may need a walking boot is for a torn calf muscle. Mild to moderate strains of the calf can usually be treated with rest, ice, elevation, activity modification and possibly reducing strain on the calf by using a heel wedge. But if your muscle is completely torn, surgery to repair the damage will likely be necessary, as the tissues cannot reattach on their own.

After surgery, you will likely need to keep weight off the leg by using crutches and wearing a high-top walking boot for a calf muscle tear like this for some time. Again, you’ll need to undergo physical therapy.

Q&A on CAM Walker Boot

  • What conditions / injuries does this CAM walker treat? The boot can be used to treat moderate to severe ankle sprains as well as stable fractures of the ankle. While the long fracture boot can be used for injuries to the foot, a short walker boot may be more comfortable. You can use the CAM walker as both a weight-bearing and a non-weight bearing walker after surgery.
  • How does it work?  The pneumatic boot protects the ankle and foot against outside forces as you recover from an ankle injury. Adjustable air cells allow you to customize the amount of compression and support it provides. This compression speeds healing and eases pain.
  • When should I wear it? You can wear the brace throughout the day for walking or while on crutches, as per a doctor’s instructions.
  • What is this splint made of? The shell and upright supports are made of metal. The brace is lined with a deluxe foam material.
  • Who can wear this splint? Men, women and some children can wear this ankle sprain boot. Refer to the sizing chart for more details.
  • How do I put it on? Start by putting your sock-clad foot in the inner lining and fasten the Velcro closure tightly. The sleeve should fit fairly snugly. In some cases, you may need to add pads to fill any gaps between the lining and shell of the boot. Next, place your foot inside the shell and slide the heel to the back of the boot. Remove the plastic covers from the upright supports and stick them to the lining. Now that the lining is secure, you can fasten all the Velcro straps of the walker, starting at the bottom and working your way up the leg.
    Washing Instructions:
    The liner can be machine-washed, using the gentle cycle, cold water and mild soap. Do not use bleach. The liner should be air dried. The shell can be wiped with a damp cloth.
  • Other features:
    • Rocker bottom and low-profile heel makes it easier to walk naturally while wearing the boot. Treads along the bottom improve traction and the cushioned heel helps absorb impact of walking and limits stress to your foot.
    • The strap at the ankle provides extra padding to this more mobile area.
    • The footbed of the walker is wide and open at the end, accommodating swelling and bandaging and improving the breathability of the orthotic.
    • The metal-reinforced uprights of the medical boot are contoured to the curves of the calf
    • The ankle brace is also fairly lightweight.
    • Sizing is based on U.S. shoe sizes, making it easy to choose the right fit. If you are between sizes, order the larger size, as you can easily tighten the brace.
    • Color: Black.
