I bought these for my mom who has knee problems and bursitis in her hip...she absolutely loves these shoes! She said they are the only shoes she can wear all day and her knees never bother her. They are very supportive and cushony (her word not mine :-)). She's worn regular crocs before (the beach kind), but over time found they tend to wear out fast. The Duet Plus on the other hand is a better quality croc, and really puts a spring in her step. She loved them so much she had me buy her another pair--I also purchased the Iris/Neon Purple color. And as for the colors, they are brilliantly vibrant! At a size 10 they also fit as expected. So they are true to size.
