Thumb-sticks are quick and feel fairly friction-less. I been riding my bike on the trails around my house and listening to my music. Its one of those boxes that typically says "some assembly required", and then you open it to find your heart skipping a beat. They are super cute and don?t look like old lady shoes. The fit was perfect, I didnt tug one strap, it was like they were made for my feet. They are really comfy and seem to be well made. For all the women out there looking for sweats, feel no hesitation in purchasing these. You don?t need to crank these to overcome outside noise. Also, I dont like not having a button to push, the touch is overly sensitive. If you want a tighter fit, get XL
