Really good quality leather and these look fantastic in this colourway.
They do run a tad small at first, but after some wear they're fine. I tend to get a half size up in 1's as I have wide feet and it allows them to stretch more.
The white soles do get a little dirty, but with all of the J1's I have a quick clean after wearing brings them up like new.
These are well worth the price and very glad I picked them up.
