With only 5% wool they’re largely synthetic, but they remain soft, they wash well, and we didn’t experience any bunching or pressure points during an 8km walk. The toe-box section is quite large, so those with skinny feet may want to try before they buy, but we were impressed given the bargain price. That said, the feeling may not be everyone: We recommend trying on a pair and running in them a few times to see how they feel. They also come with a blister-free guarantee, because the inner layer stays with the foot and the outer layer moves with the shoe to reduce friction. It’s a clever system, although they do recommend sizing down to ensure as snug a fit as possible. If you liked this article, please do share it with your family and friends.
