I knew these would be comfortable since it is Dr. Scholl's after all, but these are seriously so comfortable! Compared to other heels, it's like walking on pillows. I absolutely love these and highly recommend them! They are a little more expensive than I like to pay for heels, but I bought them with the intention of wearing them to work, so I spent a little extra for Dr. Scholl's to make sure I could make it the whole day. As far as shoe sizes, I usually wear 6-7 (usually on the smaller end) and I bought these in size 7 and they fit great.
