"I love the idea - but they are hard to insert smoothly into shoes, and then are thick enough that they make the shoes too tight."

"I love the idea - but they are hard to insert smoothly into shoes, and then are thick enough that they make the shoes too tight."
"I bought this for my Grandson who has very wide flat feet and hates wearing socks. He can’t stand them on his toes. These are so much better to just slide in his shoes. The only downfall for me was cutting them down to size other than that they’re great."
"I've always found regular socks to be uncomfortable; they are too confining. I was thrilled to discover Flat Socks! They are like being barefoot in my shoes without exactly being barefoot in my shoes. My feet are so happy! Flat Socks are the only socks I'll wear."
"Love them!"
"Love these for summer! No stinky shoes!"
"I now own 7 sets of Flat Socks! Don’t like to wear regular socks because my feet sweat."
"I am not thrilled with these Flat Socks! I tried one pair, after cutting to fit my shoe as directed, and I got a blister on the side of my foot, in a pair of sneakers that I have worn for some time. Also, my feet sweated so bad, worse than regular socks. Sorry, but I would not recommend."
"Doesn’t stay in shoes as suggested in advertising."
"Comfortable, stays put, and looks fabulous"
"Not what I was expecting!"
