I am a real person, who read a lot of reviews for these types of products and still felt like I was unsure of what to purchase: so here I am paying it forward writing about how these were exactly what I was seeking. I wear flats and low heeled shoes at work and I was looking for something to help capture sweat and prevent odor as well as slipping and blisters. These are exactly what I was looking for and a good value for 12 pair. They fit my small feet (size 6) well and the nude conforms to my foot color so it does not look too orange or too tan. It looks very natural. The black is quite sheer which is what I was looking for. They are quite thin as other said, but I have been careful when putting them on so as not to snag them. So far, I'm very happy. And for the price, if a couple snag, that's okay with me. I was also unsure how high up my ankle they would come. I am 5'1 and they come up a few inches so they are hidden under ankle-length (slightly shorter) work pants. Highly recommend.
