Believe about an ankle support for football it is important to consider the following:
How much support you will need
That it will fit comfortably into the boots
That it works with other protective gear – mainly the shin parts
Which the necessary motion at the ankle for running/manoeuvres is not reduced
First of all, let’s look at the types of ankle live or support available: IT Support
Straightforward ankle supports
These have a tendency to be neoprene or elasticated sleeves or wrap-around supports with no additional metal or plastic parts or straps. They give compression, heat retention and very low-level support, although would provide no amount of resistance against turning the ankle joint over. These are well suited for minor sprains to help reduce swelling and for many who want something warm around the joint. Examples include the Neo-G ankle support and the Vulcan si ankle support
Stabilised foot helps
These are similar to the above although also contain some form of additional support. General additions will include a lightweight steel or plastic stay inlayed in the medial part of the support, or a cross over or figure of 8 secure. For that reason extra stabilization these offer a little more support whilst remaining relatively slender line and are also generally good for small to moderate ankle sprains when returning to play. Examples include the LP775 and the Donjoy low dye strapping elastic support.
Lace-up ankle joint supports
Lace-up supports are incredibly popular and provide average to high support, with regards to the device used. They are likely as a canvas type materials which lace-up at the front. Most have a u-shaped metal spring inlayed in each side of the support. Others may have wider plastic splints or cross over strap. Many of these are bulkier than others and may reduce the necessary ankle range of motion so this should always be regarded as doing this could lead to other injuries. Examples include the Mueller universal ATF and the McDavid 199T.
High level supports
Brackets which provide the very best support tend to have a combo of stays and straps, or have very wide, rigid plastic keeps down each side of the ankle. Whilst these do provide good support, it is vital to consider the fit in the shoe and also the use of shin pads or guards with them. It is going to probably not be possible to work with the sort of shin pad containing ankle joint guards and a secure under the heel, although strapless ones may be suitable. Examples include the Aircast A60 and the PSB sports ankle splint.
Therefore, going back to the original questions:
Just how much support is needed
For minor to modest ankle sprains a simple or stabilised support should be fine. For severe, repetitive ankle sprains and fractures, a lace-up or higher level support may be required.
Will it fit comfortably in soccer shoe
Most simple or stabilised supports will fit. For lace-up and high level supports, avoid anything at all with very wide plastic-type parts down either side.
Will certainly it work with other protective gear?
This just isn’t too much of problems, although with supports with plastic stays, be ready to have to change your shin guards.
Required motion is not reduced
Lace-up supports are likely to limit the rearfoot motion into plantarflexion and dorsiflexion.
