Slitesterk Super Wool – Extra Warm Lambswool Insoles (Sizes 35–48)

Description

Slitesterk Super Wool — extra-warm wool insoles that keep the cold out all winter long

When winter really bites, the Slitesterk Super Wool is the insole I reach for. These are extra-warm wool insoles made from 100% natural lambswool, and they do a wonderful job of keeping your feet toasty even on the coldest, frostiest days.

Lambswool is remarkable stuff — it traps warmth beautifully while also regulating moisture, so your feet stay warm and dry rather than damp and chilled. That makes these insoles perfect for winter boots, walking boots and any footwear that needs a bit of extra insulation. At just £7.49 a pair, they are an easy way to winter-proof the shoes you already own.

I fit these into walking boots every winter and would not be without them. For a few pounds you get the kind of natural warmth that synthetic insoles simply cannot match, and thanks to the way wool handles moisture your feet stay pleasantly dry into the bargain.

Why choose the Slitesterk Super Wool?

• 100% natural lambswool — pure lambswool is one of the warmest natural fibres there is, trapping body heat to keep your feet cosy on the coldest days.
• Warm yet moisture-regulating — wool naturally manages moisture, so your feet stay dry and warm instead of damp and cold inside your boots.
• Soft, cushioned comfort — the dense wool pile feels soft and cushioning underfoot, adding a little extra comfort with every step.
• Ideal for winter footwear — perfect for winter boots, walking boots and work boots, anywhere you need to keep the cold at bay.
• Affordable winter warmth — at £7.49 a pair, they are a simple, budget-friendly way to make your cold-weather shoes far cosier.
• Soft, natural feel underfoot — the pure wool pile feels wonderfully soft, giving you a little cushioning as well as warmth with every step.

How to use the Slitesterk Super Wool

1. Remove the existing insole from your winter or walking boots.
2. Choose the size band that matches your shoe size, from 35/36 up to 47/48.
3. Trim carefully along the toe if you need a closer fit, using your old insole as a guide.
4. Place the insole wool-side up and press it flat right down to the heel.
5. Air them out between wears so the wool stays fresh and lofty.

Frequently asked questions

What makes lambswool insoles so warm?

Lambswool has a natural crimp that traps thousands of tiny pockets of air, and that trapped air is what insulates your feet. At the same time the fibres draw moisture away, so your feet stay warm and dry — a genuinely brilliant combination for winter.

Which shoes are these best suited to?

They come into their own in winter boots, walking boots and work boots, where a little extra insulation makes all the difference. For a snug fit, remove your footwear’s original insole before fitting them.

Are these machine washable?

I would treat natural wool gently rather than machine washing it — airing them regularly keeps them fresh, and any light surface marks can be spot-cleaned by hand and left to air-dry.
