No-one (but you) will know that these pretty, butterfly-embossed knee highs are actually 12-14 mmHg, mild compression socks. Discreetly improving circulation and easing leg strain, discomfort and swelling, they feature ultra-soft ribbed cuffs and seamless heels for restorative, therapeutic comfort. Breathable polyamide/elastane blend. Three pairs: 1x purple, 1x grey, 1x blue. One size fits UK shoe sizes 3-8.
