I am normally size 7.5. I got size 7, and they fit absolutely perfectly! I did not have a lot of trouble breaking them in, so that was great. I love these boots.
At the sale price, these boots are a great buy but not worth paying full price. I've always loved Docs but they are made way more cheaply now then they were twenty years ago. These boots are super comfy though and require little breaking in time. I am a solid size 7.5 and ordered the 8 as recommended and had to send them back. I've always been an English size 5 and should have gone with my gut but the recommendation was so convincing. I now have the proper size and I love them.
I am so glad I ordered these boots-- they're so comfortable and stylish, and I get tons of compliments whenever I wear them. They add edge to any outfit and are wonderful to stand or walk in thanks to the air soles. I would highly recommend these and am sure mine will last me a long time.
