Footbeds

 

AKU Footbeds (insoles) are original replacement footbeds designed to restore the intended fit feel of your AKU footwear, improving underfoot comfort, moisture control and stability when your current insoles are packed-out, worn or slow to dry. AKU offers multiple footbed options aligned to different use cases—from everyday hiking through to colder conditions and mountain-focused builds—so you can match the insole specification to your footwear and season. Most AKU footbeds are available in UK sizes 3–13 (including half sizes); always choose the same size as your boot/shoe and confirm the specific footbed model and size availability on the product page.

Replacing the footbed
Tip: replace like-for-like size (same as your footwear). If you use thicker winter socks, consider whether added volume changes fit.

  • Replace footbeds when cushioning is compressed, the surface fabric is worn through, or odour and moisture retention increase.
  • Repairs: Lancashire Sports Repairs only.
