Top 10 Best Insoles for Flat Feet in the UK 2021

These small leather inserts are a great alternative to a full-sized insole. If the fitted insole in your shoes cannot be removed, and there's not enough room to insert a whole extra layer, then these wedges can still be placed in your shoe to provide a decent basic level of support.

The inserts stay in place thanks to an adhesive layer, although you might find that over time you need to re-secure them with glue or tape. As they don't provide any additional support to the rest of your foot, these are not best suited to strenuous activity, but could be just the ticket for more formal shoes that you wear only occasionally.

Give your feet a fuzzy treat with these insoles from Valsole. The top layer of soft felted wool provides excellent thermal insulation during colder months, but is also breathable enough to keep feet comfortable and cool. Of course, they'll only be suitable for winter, so you'll need to buy another pair for warmer weather. 

Available in 10 sizes and suitable for any full shoe type, there's hard-wearing yet soft EVA foam under that wool layer, along with a natural cork arch support.

It's impressive how such small insoles can make such a big different to your shoes, but these super-thin insoles do just that. They focus on what's most important – firm heel support and a high arch section to raise flat feet.

There's also a breathable microfibre top layer to wick sweat away from your foot and keep you dry and comfortable. On the down side, there are only three sizes to choose from, so getting that perfect fit could be tricky.

Scholl is the household name in foot care, and as a big brand it's perhaps not unsurprising that their insoles come up pricier than most of the others on our list. The insoles include gentle arch support and aim to relieve pain by providing shock absorption, pressure redistribution and stabilisation for your feet.

They are are available in only three sizes, S, M and L, meaning there's a lower degree of customisation than you get with some other insoles, but as they only extend to the balls of the foot, they should have no problem fitting most shoes.

The 3/4 length design of these insoles features a unique cutaway section, making them even more compact and low profile. This also allows them to slide straight into most types of low-heeled men's and women's footwear.

There's a 'shock dot' in the heel to take the edge off a day on your feet, and the well-contoured form provides excellent foot contact to support and to avoid rubbing. There's seven sizes to choose from, from XXS to XXL.

These high-performance insoles from Pedag are specifically tailored for people with flat feet who require top-quality arch support during sport and exercise. As you'd expect, a lot of attention is paid to providing excellent shock absorption, and there's a series of tiny air chambers in this insole help reduce impact.

The insoles are available in 13 sizes, allowing you to get the best fit first time. And as you can expect to get sweaty while wearing them, it's good to know that they are hand washable.

The first of two insoles on our list from industry leader Superfeet, the Blue is a great all-round insole and the company's most versatile model. Highly structured, yet thin and flexible, they should fit into most pairs of shoes.

Like the Green insoles from Superfeet, these are latex-free and vegan friendly, and feature an odour-combating antimicrobial top layer. An excellent quality, versatile insole that's built to last.

Coming replete with a host of glowing reviews on Amazon, these insoles are brilliant value for the price. The two compounds in the base layer work together to provide a great combination of support and comfort.

There's also an antimicrobial top layer to keep bad smells at bay, even after a long day. They may have the word 'sport' printed on them, but these multipurpose insoles would be as good in trainers as in work shoes or hiking boots.

The first thing you might notice about these insoles is the low price, so it's no surprise to learn that they are often supplied to the NHS. Designed by leading podiatrists, these insoles are built to withstand the abuse your feet suffer from a hard day's work.

As well as arch support, there's structured positioning and stabilising throughout the entire length of the insole, with a good level of shock absorption to help reduce impacts on the heel and ball of your feet. And at under £7, you really can't go wrong!

A bestselling insole for over 40 years, the Superfeet Green offers professional-grade, reliable support exactly where you need it. As well as the arch support, the deep heel cup keeps you firmly in place while contouring to your foot to provide an excellent fit.

As a slightly more substantial insole than the Superfeet Blue and some others on our list, they're certainly going to survive many a step. Whether used alongside sports shoes, walking boots, or anything with a bit more room, they're our top pick for effective relief from flat feet conditions.
