Nike is releasing a pair of trainers which are likely to be more sought-after than Harry Beck's first sketch of the tube map.
A very limited number of trainers are being produced which feature the Johnston100 typeface — aka the tube font updated this year for the 100th anniversary of its creation.
The Nike Zoom Spiridon features a sample of the typeface, printed on the shoes.
It's not the first tube/trainer collaboration — in 2013 Nike made pairs of Air Max inspired by the old District line moquette, designed by Misha Black.
According to website It's Nice That, The Nike Zoom Spiridons will be available exclusively at a Charing Cross pop-up on 9 November, and then in a handful of "select retailers" for a short time after that.
