Designed for Comfort Around the Leg
Traditional socks can sometimes feel tight around the leg, particularly for those who experience circulation issues.
'Otto Loose Top' features an elastic-free top that provides a gentler fit. While the top is designed for comfort, the defined heel helps keep the sock comfortably in place during everyday wear.
Its medium-weight ribbed construction provides more cushioning than a lightweight dress sock while remaining less bulky than our thick, full-cushioned work socks.
Combined with the natural breathability of Australian-grown merino wool, 'Otto Loose Top' helps regulate temperature and manage moisture throughout the day, keeping your feet comfortable across changing conditions.
Whether you're at work, out walking or enjoying time with friends, 'Otto Loose Top' delivers dependable everyday comfort with a more relaxed fit around the leg.
