Our new Sweeney Vintage trainer has a unique LACTAE HEVEA sole. Farmed in a completely sustainable, ecological way, the Heavea trees are tapped for their milk, which is then refined to produce a natural, slightly translucent gum sole – tiny bubbles of air are formed in the process producing a super flexible 'walking on air' comfort. The calf leather designs are based on army trainers from the 1950s and fully lined in calf leather with a leather insock. Our Italian factory makes up the trainers before washing in giant machines, to produce a vintage, antiqued feel. Once washed, the uppers are coloured by applying layer after layer of dye by hand, before antique polishing.
