Hop Hare's low trainer sock in the Rune Stones design, with ancient Norse rune symbols. Made with 70% bamboo, they're soft, breathable and cut low enough to stay hidden in trainers, so you get the design peeking out only when you want it to.
Two sizes: UK 3.5–6.5 (EU 36–40) and UK 7.5–11.5 (EU 41–46).
There are plenty more designs in the Hop Hare range, including Phoenix, Lunar Phases, Moonlight Wolf, Hamsa and 7 Chakra, so you can build up a drawer full.
