Karhu remains in the limelight in the world of running with the new edition of one of its most characteristic models, the Karhu Fusion 4.0, a model designed to run on asphalt with safety and comfort in equal parts. A new edition of one of the longest-running ranges within the company and that comes with some of the most important new features without losing its philosophy.
And these Karhu Fusion 4.0 are running shoes that come to market with some of the best technologies and materials of the company, something to which we are already accustomed. A model of perfect performance for asphalt running that stands as one of the great options of the season within the sector in the company.
The Fusion 4.0 are Karhurunning shoes designed to offer the maximum feeling of comfort in all types of training sessions and races. Its AeroFoam midsole made from infused nitrogen favors a comfortable and safe run in equal parts, with a high degree of dynamism in each step. In addition, the Fulcrum + Propulsion system will offer an efficiency never seen before in the model.
For its part, we are facing a model that, as in previous versions, stands out for its Ideal Knit upper, a soft and breathable mesh with a perfect fit that, along with the M-Lock lacing system of its lacing, will keep your feet in the best possible condition for the practice of running. A model that comes with 302 grams of weight and a drop of 6 millimeters already characteristic of the Fusion line.
In terms of ideal profile, the Karhu Fusion 4.0 is a shoes with maximum versatility and adaptability. We are talking about a medium build model that will adapt perfectly to all types of runners, even those heavier than 85 kilos. In addition, it should be remembered that this is a model suitable for everything from light training to demanding competitions.
Of course, we are talking about a model of medium paces, which will surely allow us to run at a good pace in all kinds of situations, yes, but without offering too high a speed at any time, that is, without standing as a model nestled in the block of flyingshoes.
As far as target distances are concerned, with the renewal of the previous Karhu Fusion 3.5 we are looking at a model for medium mileage. Specifically, a model for distances of all kinds, from short and somewhat more explosive sessions to even marathon competitions at a calmer pace.
In short, running shoes for men and women stand out for their versatility, for being oriented to runners of all types who seek to face a wide range of distances at a calm pace and without too much effort. A model that despite not lowering the barrier of 300 grams is very close, and with which, thanks to its 6 millimeters drop, you can enjoy a more natural tread.
