Wow, Im am so impressed with this tiny speaker. Cute sandal, but even on the widest setting, I couldnt get my foot in! Not to childish, colorful, and nice to slip on and go. This is by far the next best thing. Grandson is extremely satisfied with his purchase. Si me podrían ayudar, no lo quiero devolver, solo cambiar y asumo el $$ que se necesite. The seller offers great customer service and communication also. And if they get wet they dry quickly. It is not easily seen through either, which is a plus. Our slippers get a lot of wear - daily use - and we consistently get 3-4 years out of a pair before needing to replace.
