We haven't tested the new Mammut Sertig Low shoe yet, but it sounds like one to keep your eye out for. We'll have a test for you soon but in the meantime Mammut tell us it has been developed for ambitious mountain training on changing surfaces. It sits close to the foot, is lightweight and offers effective cushioning, making the shoe ideal for different speeds and distances.

It weighs just 255 grams, and has a seamless tongue construction designed to prevent pressure points. The Advanced MTR Speed Lace System allows to make lightning- fast adjustments to the laces during the run, ensuring a perfect fit at all times. Surplus ends of laces can be tucked out of sight in the blink of an eye.

Another highlight is the patented Rolling Concept. Thanks to this sole concept developed according to orthopedic principles, optimising the foot's natural rolling behaviour thus reducing fatigue - and therefore the risk of twisting an ankle. Sounds good, watch this space for a full test.
