I have been searching far and wide for a comfortable, supportive and stylish shoe for a very long time. I came across the brand Jambu and have tried a few of their styles before. The Cali is by far the most comfortable one yet though. I also have a pair of softwalks that are very comfortable but not very pretty. This shoe is attractive and as comfortable as my softwalks. I am a hairstylist so this is always an issue finding a comfortable shoe that I can stand in all day long but that also looks professional. I would say that the shoe fits true to size. I am usually a 6 but standing all day my feet do expand so I have learned to always buy a half size bigger for work shoes. My heel does slip a little in the back but over the course of a few hours it fits perfectly. Happy shoe shopping...give the cali a try though I don't think you'll be disappointed!
