I received this sandal in a timely fashion.  I love it because its very similar to my daughters transportation 3D image one that we purchased before.  We loved hers so much that I thought it would be awesome to have a pair in my size!!!! They had it, how awesome!!  They are completely waterproof and super easy to clean.  They are adjustable from the back and top and even has the magnetic closure just like the toddler/kid sandals.  I really like that about this product.  I do wish the back would tighten alittle more than it does because they do run alittle big for me, maybe by half a size so my foot flops around alittle but it's not a huge deal to me.  There is an option to take the back adjustment off completely and wear them like a slip on.  They do seem to have good traction so I feel comfortable wearing them around water and pools.  They are light in weight and attractive. I would recommend these to others because they are simple, easy to use, easy to clean, waterproof, and just fun!!! The magnetic feature is my favorite, no worries about tying loose shoe strings!!! Its fun for adults too, not just kids!!!!!!
