I do not recommend these flip-flops. Following the recommendations, I ordered a larger size, but my heel barely fits, and the front sticks out by a few centimeters. One of the flip-flops is well made, while the other looks like someone was just learning or adjusting the production machine. The narrowing between the toes is poorly fused, causing sharp edges to stick out, which leads to chafing. I had to smooth them out with a knife and melt them with a lighter, but the pin inside is shorter than in the other flip-flop, making the foot fit very tightly and chafe the top of the foot. They are unusable. One photo shows the correct workmanship, while the other shows the defective one.
