For obese and burly these socks are unfortunately unsuitable. I have an extra size 47-50 ordered in black. Nevertheless, they are too tight, especially at the waistband. What I also do not like, they are very smooth in structure. In flow, laminate or hardwood floors running becomes a skating trip. Particularly hot they do not keep your feet too. Next time I will order again Tobeni health socks, much more comfortable and soft to wear.
