AEROTHOTICWomen's Orthotic Comfort Thong Style Flip Flops Sandals With Arch Support For Comfortable Walk

Can anyone compare these to Oofoos, which are super comfortable?

I got a rash from the top straps on both feet, not sure why. Has anyone else had this problem with this product?

I'm usually an 71/2 8 shoe. What is the best size for me? Should i order a 8?

Where areaerpthotic sandals made?
