Example Output: 1

Example Input: These socks with treads fit well. My only issue is the placement of the non skid rubber bumps. They are placed primarily on the arch of the foot area. That area is the least used and caused the heel area to be more slippery. The toe area would have helped with crawling but was again slippery. They are very cute and the strap helps keep them on the feet.
Example Output: 4

Example Input: I haven't used it yet so I can't speak to the quality, but the photo shows an assortment of colors. What I got was 6 gold, 4 brown, 1 gold/brown mix, 2 silver and the other 7 were mixed colors. not at all what I was expecting.
Example Output:
