Comfort!  It looks attractive, too.  This pair of sandals supports the feet and arches. The entire foot bed is cushioned with thick memory foam. Visually, it doesn't look thick.  Actually, it doesn't even look cushioned. Oh, but it is. The foam is built down into the footbed.  While walking, the sandals absorb quite a bit of shock, too.  For sure, my knees feel much better when wearing.  I really appreciate the relief.

Clarks did a fabulous job with the design of this sandal.  Specifically for people with joint problems in the lower limbs, this sandal forces you to keep your weight distribution in a more proper alignment. Even when just standing, the design won't allow for shifting your weight forward, stressing the knees even further. While walking, the design forces you to stand straighter and destribute more weight to your heel, while providing deep cushioning and the addition of a built up heel on the sandal for support. I think people with mild hip joint problems will benefit, too.  I'm a clinical massage therapist.  I understand movement and proper posture alignment.  I have arthritis in my knee joint, so I also understand pain will cause most people to change posture, even if that change throws off proper alignment and over time creates additional problems. Many people with knee joint pain will shift weight forward to prevent impact pain while walking. This sandal is a supportive helper.  It cushions impact, while it propels a more properly aligned stride. The overall benefit is more comfort and less pain. I highly recommend.

The thong is comfortable, too.  Even people that don't normally wear thong sandals will probably find this one comfortable. The thong is made of fabric, and the design of this sandal doesn't allow it to push deeply between the toes. The sandals encases the foot very well. You don't have to scrunch up your toes to prevent sliding. The sandal's design prevents the feet from sliding forward and backwards.  Your feet stay in place.  They have a non skid sole. It's a true to size medium width.

This is not a leather sandal. It's constructed of made made materials. The strap design the crosses the foot is completely padded underneath. While wearing, my entire foot feels the comfort.

UPDATE:  As of this review, Amazon is selling the "Clarks Seymour Drive Flip Flops" for about 17 bucks less than these. I purchased those, too. I wanted to save a few bucks. You won't save anything purchasing those. I returning my purchase. Visually, the styles look basically the same, but the fit is different.  On the "Drive Flip Flops", one sandal has less depth than the other in the footbed. I can feel the difference while wearing....it feels like I'm wearing two distinctly different shoe heights on each of my feet.  I certainly don't recommend the Drive Flip Flops.  They are poorly constructed.
