LLSOARSS Plantar Fasciitis Feet Sandal with Arch Support - Best Orthotic flip Flops for Flat Feet，Heel Pain- for Women

Where are these made?

Does anyone else have a problem with these sandals making their feel stink?

Are these men's or women's sizes?

Are these essentially Chinese couterfeit Orthaheels? The tread and the soles look exactly like my pair except the brand name is missing on the tread.
