So, if you are planning to buy a new pair of quality thermal insoles before the winter hits hard, read on to know about our product recommendations and buying guide. Let’s get started!

Best Thermal Insoles UK 2020

Given below are the top ten that you will currently find in the market.

1. Kaps Natural Wool Shoe Insoles

If you have been looking for woollen insoles, then this product from Kaps will not disappoint you. The best thing about these thermal insoles is the materials used and manufacturing quality. These are made of high-grade, natural sheep wool which are super soft. So, it heats your feet up even when the temperatures are really low. The bottom of these insoles is made of soft latex foam, which ensures that you are not uncomfortable while walking around in these insoles.

Now, let’s talk about the size since the brand claims it to be made for all sizes. Well, that claim is absolutely true because these are pretty massive, and there can’t be any shoe that these won’t fit in. Just follow the cutting guides and cut the size pad according to your need. The maximum length you’ll get is thirty cm, which is more than enough.

The thickness of the insoles is just right to stop you from getting cold feet without making them uncomfortable or sweaty while walking.

  • Latex foam bottom to ensure comfort
  • Big enough to be adjusted for all sizes
  • The right thickness to keep you warm
  • Easy to walk around without getting sweaty feet
  • The quality of wool needs to be better
  • Too thick to be used on shoes that are a snug fit

2. Kaps Alu Super Triple Layer Shoe Insoles

Another great offering from Kaps, this one is a thermal insole that assures you of both comfort and warmth. It is a warm and soft shoe insole that has three layers to give you the maximum protection. The top layer is made from warm fabric, the middle one has insulating foam, and the bottom layer is foil to prevent cold from entering your feet when you walk.

Just like the previous product, this one also fits all sizes, and you will just have to cut it according to the size that you need. The maximum size is 12 UK, which is enough, as per the average shoe sizes.

A good thing about these insoles is that stops you getting cold feet but won’t let them get them to hot so they become uncomfortable and your feet start sweating. Wear these inside your work shoes or wellingtons, your feet stay toasty warm. The fact that it moves a lot inside the shoes might be an issue, but that’s nothing that a little glue can’t fix.

  • Three layers for added protection
  • Can be cut to fit all shoe sizes
  • Comfortable to wear for long hours
  • Reasonable price
  • Tends to move a lot inside the shoes
  • Not suitable for extremely cold weather


Next up on the list is the Woollen Winter shoe insoles by Kaps, which come with the same promise of quality as their previous two products. In fact, this one is a notch above the others because it is made to offer you protection from extremely cold temperatures. The insoles are good to go with winter boots and shoes as well as trekking and outdoor shoes having climatic membranes.

In terms of the comfort factor, the top layer is made of completely natural and high-quality wool that makes the insoles cosy and warm. The bottom layer has aluminium which keeps your feet insulated against the cold. It also has latex foam infused with charcoal to control odour. So, no more smelly feet problems!

Unlike the previous insoles from Kaps, you will have to choose your size for this one. It sure helps when the insoles take a fits-all approach, but even then, the size variety is good enough to get you what you need. The insoles deliver an exact fit, so don’t think of buying a size up or down.

  • Make to offer protection from extreme cold
  • Aluminium bottom layer for effective insulation
  • Contains charcoal-infused latex foam to control odour
  • Comfortable and cosy to wear during the winter
  • Not a very durable product
  • Tends to slide to the front

When the aim is to prevent any cold from coming up through the shoes, these winter insoles by Blackrock can come to your rescue. From cycling and skiing to simply walking down the lane, you don’t have to let the cold winter stop you from any activity once you slip these insoles on.

The aluminium foil-based insoles reflect the cold away from your feet to make sure that your work does not have to suffer due to the harsh weather. There is also an added layer of foam to bring thermal insulation to the insoles. For extra comfort, you have a felt covering on the shoes.

When it comes to the size, the product takes the made-for-all approach like most of the modern thermal insoles. You just need to cut it according to the cutting guide to trim it for your size.
