Thank you for viewing. These socks are knitted with a mix of wool and polyamide, using Opal yarn, fingering weight. The size is approximately 23cm to 24.5cm, with a width of 9cm, and a height from the heel of about 14cm. They have a gusset, so they can be worn by people with wider feet or high insteps. They can be machine washed using a laundry net. These are handmade by an amateur, so please understand. Please refrain from purchasing if you are looking for perfection like a commercial product, or if you are meticulous.
