There's a particular kind of guilt in owning a pair of trainers so good you're almost scared to wear them. Jason Markk exists for exactly that dilemma. It started with a simple gripe from founder Jason Mark Angsuvarn: there was still nothing made specifically to clean trainers properly, so people reached for whatever was under the sink instead. His answer was the Premium Shoe Cleaner, a biodegradable formula strong enough to lift dirt from leather, suede and canvas without touching the colour beneath.

That same instinct — do the job properly, without the harsh stuff — runs through the whole range now: a water-based Repel spray that actually works, suede kits, and a refill scheme that means the bottles get reused rather than binned. It's also B Corp certified on top of that, looking after the planet with the same care it gives your shoes.
