Are insoles supplied in pairs?


Yes. They should also be worn as a pair unless specifically advised otherwise by a clinician. Insoles will create posture improvements that are best mirrored to both limbs. They can also generate slight elevation changes.




When we talk about sizing we are referring to foot size, not shoe size. UK sizing is unisex, regardless of perceived differences between men’s and women’s shoe styles and sizing.


It is essential that the insoles fit your feet and conform accurately to the arch of your foot, so order whatever size you believe your feet to be. Once you get them, do a quick test before putting them in your shoes. If you stand on them, there should be 8-10mm extending beyond your longest toe and they should visibly fit your arch.

How soon will I receive them?


The Salford Insole is manufactured in the UK and will be shipped by Royal Mail, so you should expect to receive them within 2-3 days. UK postage is included in the price.

Why might I need insoles?


Most of us would benefit from arch support insoles. Our feet are not designed to walk on hard surfaces and most footwear lacks adequate support. Our feet are designed to pronate but not over pronate (or flatten). There are a number of pronation related conditions of the foot, ankle and knee, that can be eliminated quickly and permanently by effective arch support.

Should I wear them all the time?

Yes, or at least whenever practical. Your feet will benefit from arch support whenever you are on a hard surface, whether running, walking or even just standing. This includes around the house, which is often overlooked (slippers are mostly ineffective).​

Should I remove any existing insoles?


Yes. Our insoles are designed to provide all the support you need. Any existing insole or liner will just distort the effect.

How long will they last?


Indefinitely. They carry a lifetime wear guarantee and will function consistently, indefinitely. You will never need to replace them and they can simply be moved to new shoes.

What does “evidence-based” mean?


The geometry of the Salford Insole was proven during two years of patient trials. The features that contribute to its effectiveness can be viewed below in the features section.


How long has the Salford Insole been around?


We’ve been supplying the NHS and the professional podiatry profession for over fifteen years. Since the first lockdown associated with COVID, we’ve made this device available directly to the public. You will be investing in a tried and tested intervention that will last indefinitely.


Should I get soft insoles for extra comfort?


No. A lot of marketing material promotes soft cushioning for pain relief (particularly in the case of Plantar Fasciitis), but this is targeting the symptoms and not the cause. Firm is best for active people.


How important is footwear choice?

Very. Footwear should be well fitting and fit for purpose. Most footwear is produced cheaply, with only notional attempts at providing effective arch support. Footwear choices should be made with insoles in mind for those of us that would benefit from them.




Arch shape is critical. The Salford Insole is anatomically correct, having been cast off a foot during a structured, two year project that studied how to prevent conditions that are related to over pronation of the foot. Insoles that span several sizes have insufficient arch support.




The deep heel cup ensures that the foot’s fatty padding is positioned underneath the heel, providing natural shock absorption.



Individual sizing is essential to effectiveness – we don’t buy shoes that are S, M & L and our feet are not measured to be, for example, size 6 - 8.5 as many insoles are sized. People between sizes can use either the size above or the size below. Always prioritise fit to the foot as opposed to what size different manufacturers say their shoes are. Adult feet do not change in size.



  • Length - Shorter insoles (called ¾ length) can move around in footwear, lessening their effectiveness as the features of the insole become misaligned with the anatomy of the foot.


  • Shape - The signature shape of the Salford Insole was developed to fit in the widest possible range of footwear. This involved extensive trials and visits to shoe shops!


  • Thickness - The Salford Insole is as thin as it could possibly be made, with fit in shoe being an absolute priority.


  • Cover - Top covers are unnecessary and simply harbour bacteria - socks will wick away sweat from the foot. The Salford Insole is machine washable.


  • Material - The material was developed specifically for this product. It needed to be firm yet flexible and to function consistently and indefinitely. The Salford Insole has a lifetime guarantee and is also 100% recyclable.


  • Weight - For the boffins out there, the material has a specific gravity of 0.97, meaning the insoles will actually float in water. Weight was a major consideration for sports users.
