We?ll try the next size up and hopefully they?re not way too big (sometimes between side 13 and size 1 I find there?s a huge jump in length) Just down to earth people putting out professional quality work for all of us to enjoy! i worked in fire alarm testing and they were invaluable for bell tests on and off all day. The material is 100% cotton, and its on the thick side. I wore them on a cruise and did a lot of walking in them. If the adhesion stops I will edit the review.
