Because the description here on Amazon didnt provide a lot of information. I got it as a gift for my friend. the fabric was somewhat thick - great quality! Easy to pair with any device. 10/10, A+, 100% They are so comfortable, stylish, affordable, and the straps fit perfectly over my feet (not too tight, doesnt rub). Overall, this little thing completed my setup and was a delight to play with. Also if you are on a weigh loss journey like the rest of us, don?t order anything too big that won?t fit in a month; that?s just a waste of money. I ordered size 5 and they fit perfectly. EDIT the seller reached out to me and addressed the issues offered to replace it with a different product it got to me the next day after they reached out and the new product works great.
