Barbed wire dipped in acid. Irate fire ants. Shattered glass coated in salt. LEGO bricks. All materials you wouldn't want your shoes to be made from.
But fear not - you're not supposed to wear the creations of Tom Yoo. A master builder and self-confessed sneakerhead, Yoo's range of brick court shoes first caught the attention of the internet's shoe obsessives earlier this year when his Air Jordans surfaced.
Originally just one-off creations, Yoo's use of LEGO bricks to create classic silhouettes had many asking for instructions, or the option to buy his own creation - and finally, Yoo has relented.
In festive spirit, he's selling a set of his own models (fully glued to ensure they don't come apart in transit) with prices starting at £1,344. Ten per cent of all sales will be donated to the Downtown Women’s Center and the Union Rescue Mission of Los Angeles.
Take note - you'll only receive one shoe, as Yoo doesn't create matching pairs. You'll have to rely on your own building skills to make the opposite trainer.
