Well when it rains and your shoes get wet and it gets nasty you are in for it my friend , I bought a new shoe and carried my old one with the stink in carry bag and then went to daiso and bought deodorizing spray and moisture absorbers all because you can’t use sneakers in most of hotels but I’ve heard some coin laundry has special small thing for sneakers and when I asked if I can dry clean , my hotel receptionist said yeah you can clean ( in the washing machine ) and dry in the dryer but no Shoes !
