THESE ARE THE COMFIEST SHOES EVER! For any type of activity - these trainers are what you need! I cleaned them up a bit before this photo and literally any/all dirt comes off the white sole wth a wet cloth (as seen in pic 4). I've never had them through the washing machine but I'm so confident if you did then they'd come up like new. I'm a UK size 6 or 7 depending on the brand and these fit nicely. I'd say they would also fit half a size bigger as the upper material is so flexible.
