The classic slip-on, thoroughly modernised The Jungle Trek Mule takes a Merrell icon and gives it a genuine design refresh, trading the boxy original for a sleeker, more design-forward silhouette without losing the comfort that made it a classic in the first place. A neoprene stretch collar means you can step in and out without bothering with laces, while the suede leather upper adds a bit of texture that looks as at home with jeans as it does on a gravel path. The FloatMax foam midsole gives a genuinely soft, smooth ride underfoot, and Merrell's sticky rubber outsole grips when the pavement turns to mud or the mud turns to wet decking. Available for men and women, it's the slip-on for people who want trail comfort without looking like they're about to go up a mountain.

Keeping shoes out of landfill - Merrell has committed to saving 300,000 pairs of shoes from ending up in landfill through its dedicated recycle and resell programme, extending the life of footwear and reducing waste. Sustainability through recyclable materials - This product is made with recyclable materials. Merrell started in 1981 as a custom bootmaker in Utah, and it's fair to say the fit stuck. Four decades on, their reputation for out-of-the-box comfort, no-nonsense hiking boots has made them the biggest name in the game worldwide, and this season's lineup shows why they haven't stood still. The Cham Redux and Moab families take Merrell's trail heritage and rework it for daily wear – genuine GORE-TEX waterproofing and Vibram grip, but built for a wet dash to the shops as much as a soggy Sunday on the Downs. There's still a slipper-soft moc for padding round the house, and a rugged trail runner for anyone chasing PBs on muddy singletrack. Whatever you're doing outside – or getting to and from it – Merrell's spent 40 years working out how to make it more comfortable.
