pre-order only atm, shipping in August, though End has another version available now in canvas with a spotty interior (but more expensive):
Just bought a pair of these...
They're on sale at 6pm for 40 bucks... never had any experience with PF Flyers but these look really nice to me. couldn't pass for the price.
I love almost everything Fred Perry. Some of my favorite plimsolls. The logo is so clean
