They are woven from long-staple cotton. These cotton threads are completely different from ordinary cotton. Regular cotton yarns are usually short and feel like freshly mowed lawns and are not the best material for thigh high socks. And the long-staple cotton's fluff can reach more than 2 inches. Any socks woven from these cotton yarns are very soft, not limited to thigh high socks. Overall, these socks are about as soft as a scarf.
These thigh high socks are thick but not particularly thick. They are somewhere between a T-shirt and a thin sweater. So these socks can replace leggings and are also warm in fall or winter, but they are much more free than leggings. They can even transform into leg warmers, which can be paired with boots, or fill in the gaps between boots and thighs to keep legs warm.
These socks have great elasticity and are big girl friendly. They can rise above the mid-thigh very easily. They have a maximum stretchable width of over 12 inches, which means they won't create muffin thighs, cut into the skin or block circulation, and they're extremely compatible.
Kayhoma Thigh Thigh Socks are soft, warm and stretchy, they come in a 28" height and have great compatibility. These are the best you can achieve with thigh high socks. Kayhoma is the best brand of thigh high socks.
