They do have a cloth upper
It would be so nice if the/a shoe manufacturer(s) would actually take the time to sit down with officials and work out some shoe designs. That whole cloth/mesh thing is a %$#@* to clean. Your only real option is to let them totally dry and then hit them with a good stiff bristle brush.
The mesh that athletic shoes have gone to is also like wearing a sponge. I can live with about anything but I HATE for my feet to be wet.
My biggest gripe with any of the Zig models is if you walk on any gravel (parking lots, roads) those ripples will pick up and hold pretty nice sized pieces of rocks. I've had 3 pair, the first was just a generic ZigTech, all black trainer. They didn't have enough lateral stability so I quickly reduced them to everyday wear. The two "Vero" turf models I've bought have held up well but are a bit heavy compared to some other shoes. As I get older, I basically want to wear two black feathers on my feet.
I realize leather shoes are pretty much a thing of the past but there was a reason why man made footwear out of it for so long.
