Keen announce new Bellows Flex technology for 2021

Written by

Press Release: KEEN, have announced their all new BELLOWS.FLEX collection for 2021, with two new styles premiering for SS21; the Tempo Flex and Ridge Flex.

As a brand that continually seeks to lead the outdoor industry, KEEN set out to create the most efficient hiking boot on the market. When the foot is in motion the forefoot compresses, which when combined with overlaying materials typically used in conventional boot construction, creates flex points that not only consume energy, but also can lead to premature failure of boots in this area. The addition of the accordion like KEEN.BELLOWS FLEX technology to this critical area enables hikers to move with less effort, leading to easier days on the trail and many more miles of comfortable performance during outdoor adventures. When tested against similar boots in the hiking category, KEEN.BELLOWS FLEX hikers on average required 60% less energy to bend, contributing to increased efficiency and comfort with each step.

With a striking, trail ready silhouette , the Ridge Flex WP is constructed in premium, environmentally preferred leather sourced from LWG-certified tanneries that operate on a closed loop basis to reduce water and energy usage, an industry gold standard that completely eliminates waste water. A KEEN.BELLOWS FLEX insert in supple yet robust TPU provides additional durability in the forefoot,  for increased efficiency and comfort with every step.  The upper has been further treated with a PFC-free durable water repellent that is safe, effective at repelling water and dirt and non-toxic, so protecting the planets’ sensitive ecosystems. Inside the boot, a pesticide-free Eco Anti-Odor treatment uses only natural materials to break down odour in sweat, eliminating pesticides and biocides from going into the environment, so feet stay as fresh and clean as your conscience. A speed lace system allow for a precise and snug fit, whilst a heel capture system and underfoot shank ensures reliable stability and protection on technical terrains. A KEEN.DRY membrane keeps feet dry and comfortable in all conditions, while the KEEN ALL.TERRAIN outsole is equipped with rugged 5mm lugs for sure footed traction wherever you roam.  Choose from a mid (£150) or low-cut (£140)  model in men and women’s specific editions.

The Tempo Flex  WP(Mid, £130, Low £120)) is the ultimate choice for those seeking an agile and contemporary hiker that delivers total performance in both look and feel.  This fast and light hiker features a performance rip-stop mesh upper with TPU overlays for durability and KEEN.BELLOWS FLEX insert to make every step on the trail easier. Designed to perform in all conditions, a KEEN.DRY waterproof and breathable membrane has you covered whatever the weather, whilst KEEN’s super rugged ALL.TERRAIN Outsole delivers incredible traction on the toughest terrains. 

A speed lace webbing system with adaptable top collar hooks ensure a comfortable and secure fit, whilst an underfoot stability shank provides lightweight yet reliable protection when moving at speed.   As always, KEEN innovates without compromising its values, with the Ridge Flexconsciously created with PFC-free water repellency with zero toxins and featuring pesticide-free insoles for natural odor control. Going the extra mile for sustainability, the Tempo Flex also utilises recycled PET throughout the protective rand to the side and front of the shoe for extra durability, making your footstep on the planet even lighter wherever you explore this summer.
