Who should buy the KEEN Tempo Flex Waterproof

The Tempo Flex Waterproof is by no means a tough sell. That being said, it pays to know more about it before leaping on its bandwagon. You are its main audience if:

  • You highly value footbeds (stock ones, in particular) that give incredible arch support.
  • The trails you visit are often ladened with inch-deep puddles.
  • Your hikes include lightly muddy inclines and soft-soiled terrain.
  • A combination of rearfoot mobility and heel stability is what you're after in hiking shoes.

Who should NOT buy it

For a more forgiving forefoot fit, look in the direction of the Oboz Sawtooth II Low BDry instead. If your tootsies sweat easily, you're better off with the non-waterproof Danner Trail 2650.

Tempo Flex Waterproof: Built to move

Forward momentum is core to the Tempo Flex Waterproof’s existence. Just look at its forefoot—yes, it easily resembles Kylo Ren’s pretty iconic helmet. But to cut to the chase, this ridged part of the shoe (a.k.a. KEEN.Bellows Flex) gives springier push-offs minus that feeling of awkwardness at the flex point.

This exclusive tech, however, is not alone in making the Tempo Flex Waterproof such a propelling piece. Yes, boosted strides are yours in this agile KEEN hiker, thanks in part to its highly flexible collar and moderately rockered heel and toe zones.
