In 2014, Puma collaborated with Ronnie Fieg and Dover Street Market for the release of the Ronnie Fieg x DSM x Trinomic XT2+ in the 'Achromatic' Pack. This exclusive shoe, available only at Kith and Dover Street Market, presents a minimalist white colorway, made with a striking combination of premium materials. The upper is meticulously crafted using a top-notch Italian glove leather, complete with the traditional TPU forefoot harnesses and lace locks, while the inner lining, footbed, and quilted inner-tongue flaunt a plush velvet pig leather. Providing exceptional support, the XT-2's midsole unit utilizes Trinomic-technology in a honeycomb design.
