The most difficult to scrub out of an open wound is the fibres of the jean/pt broek and t- shirt.
A denim only last 0.005 seconds before your are being grated like cheese.
I have the scars for life.
I have the same in black as my work commuting shoes.
Actually 2 pairs, bought the first pair on my normal shoe size, an they are just a tad to small. One size up and new ones fit perfect.
