Merrell's iconic Hydro Mule gets an update, equipping the silhouette with technology established from making the world's best hiking boots.

The BLOOM foam uppers are made using algae biomass—turning dirty water into clean during the process—sporting the recognisable design that ruins every trypophobe's day. This edition also features a unique wear-off finish which gives the effect of being painted.

The midsole has been updated with FloatMax foam for a soft and smooth feeling, giving these a lot more functionality outside of kicking around the house.
