Manufactured according to UK sizes, to which they are true. The last is fairly wide and the toes have a generous allowance. If you want a tighter fit, consider half a size smaller. Pro tip: if you already own Salomon Forces series footwear, these seem very close to their sizes in our experience.

The correct conversion to US standard sizes is to add one, I.E. UK 8 is the same as US 9. (The mfg labels on the box may refer to a different standard, please look at the UK sizes only.) If you know your European shoe size or foot length in millimeters, look at the chart below for better conversions.

Please note!The chart is based on hard facts about shoe size conversions: Paris Points, Barleycorns, and such. When you receive the boots, you may notice that the box and boot labels may not be the same as we indicate. The UK size is correct across the range so use that to verify what you have.

Warranty

Aku footwear has a 24-month warranty for material and workmanship. It goes without saying that we at Varusteleka don't let customers down; in this case, the manufacturer is also part of the chain that keeps you going.

Care and warranty

We recommend that you read ourshoe and bootcare article. In a perfect world, you'd let your boots dry for 24 hours with the insoles and laces removed after using them. Your footwear will last longer and work better if you alternate between pairs. Obviously, don't take this too literally and use common sense applied to your situation.

Clean dirt off the boot with lukewarm water and a brush. Avoid aggressive detergents, at most go for some mild detergent. Dry at room temperature.

Before the boot is fully dry, impregnate with a spray-on protector and/or treat them with care creme on a moist sponge. The treatment soaks into the fibers of the material, making it water and dirt repellent. Contrary to intuitive thought, this doesn't make the footwear less breathable: wet and dirty materials are the poorly breathing ones.
