I was sick and tired of buying cheap foam flip flops that last about a month, so I did a lot of research on flip flops that would last a long time, and tons of reviewers said that their Reef Sandals have lasted them years. The birkiflor is synthetic & immediately super-comfy & clean easier, but begin to look worn after about 8 years as opposed to 20 years! Looked material and pic nice buy Definitely get the handlebars Grip is ok. Once home I noticed some sunscreen residue and minor dirt so I threw it in the washing machine and dryer and it looks brand new again. Some people complain when they try and clean their wheels once a year by spraying it on and rinsing it off in less than a minute. Not only do I feel clean, but I also feel the moisture really soaking into my skin. all day inside and moderately outside around the driveway/porch/deck. Gave them to my husband to use as a shower shoe when he travels for work.
