Size Guide


Barefoot Footwear Size Chart

Zero-drop, wide toe-box fit — measure your bare foot from heel to longest toe for the best match.

How to Measure

Foot Length: Stand on a sheet of paper, mark the back of the heel and the tip of the longest toe, then measure the distance between the two marks.

Toe Room: Leave about 0.3–0.5 in (0.8–1.3 cm) of growing and movement room beyond your measured foot length.

Notes: Adult shoes use unisex sizing — most men's sizes match the unisex size directly, while women's sizing runs one size larger (example: Size 8U fits Men's 8 / Women's 9). Measurements are approximate; if your foot falls between two sizes, choose the larger size for a roomier wide toe box. For children, allow extra growing room when selecting a size.

"Why are most socks angled inward at the toe box when toes naturally want to point forward? Why not just make socks the same shape as feet?"

These simple questions led to the creation of Plus12 socks. Shaped like your feet, these wonderfully soft merino wool mid-calf socks are shaped to allow your big toe to stay in line with the rest of your foot. There is still plenty of wiggle room for the rest of your toes, too!

Combined with high-tech fibers, these merino wool socks are breathable, fast drying, temperature regulating and luxuriously soft. This high-performance material is ideal for both warm and cool temperatures. Oeko-tex certified (ensures safety in textiles) and mulesing-free.

  • Content: 40% merino wool, 40% polypropylene, 18% polyamide, 2% elastane
  • Padding: smooth (light and airy)
  • Length: mid-calf
  • Country of Origin: designed and made in Austria.

Plus12 merino wool socks can be machine washed, but we recommend washing them inside-out using cold water on a delicate washer setting. To prevent damaging the wool fibers, do not bundle with clothes that contain zippers or rivets (such as jeans). For optimal care, wash in a mesh laundry bag.

After washing, stretch gently into shape and hang to dry.
