These are really great looking sandals; I wish they had worked out for me. I had a few pairs of ADIDAS sandals with the little nubs on them growing up but the nubs would eventually fall off one by one. I didn't mind because they were still comfortable. The nubs on these seemed a little more resilient but they were a lot less comfortable, even after a week. I love the look but I had to return them and try something else. Too bad.
