In my 20th year of living with constant back pain & radiating spasms, shoes are a truly important part of healthy living. It is about way more than simple comfort. Now that one knee is in need of a replacement (Osteoarthritis), the Jambu Bloom has been a revelation! Owning many dozen pairs, there can't be too many built-for-comfort/orthopedic/pain-relieving shoe brands that have been overlooked. After ordering 2 duck boots from Jambu that were too large (in my regular size) I was wary of ordering shoes that left me swimming in them. I sized down, by 1/2, and it turns out I had to return these for being too small. Finally, re-ordered in my regular 9.5 and the fit is perfect. So g-l-a-d that I ordered these Jambu slides! Between the super comfy insole and the 'bounce' of the shoe bottom, it's hard to know which makes the Bloom fit like a second skin. The criss-cross top of the shoe is velvety smooth resting on the top of the foot. It is genuinely like "..walking on air..." Is it obvious that I'm a fan? I just LOVE this shoe!
