Bought these as my 4 teenagers are terrible for wanting and getting white trainers dirty much to my dismay ????.
The bags fit a pair of size 10 trainers in easily and are padded enough to protect them through the wash cycle. I have also used then for size 9, 8 and 6. All with good results.
Did put 1 towel in the wash as I wasnt too sure but I dont think I needed too. No knocking, no damaged trainers but more importantly no dirty footwear!
