Thank you and Amazon The first day I wore them, I felt like a tiny piece of glass was stuck in my foot. I can imagine the more I listen, the better theyre going to sound. I also have a pair of Skullcandy Crushers for when I want a pair of car subs attached to my ears and Jaybird X3s with Comply tips for skating and exercising. But all in all it appears to be pretty sturdy . I should let you know that I like my shoes to grip my upper foot fairly tightly. I hope you are not stuck at 10. I thought about getting another pair of Sambas. I love these shoes so much, after owning a pair for almost 8 years I was heart broken when I wore thru the sole at my toe. I LOVE these Shoes!
