Black Diamond Contact Strap

The Black Diamond Contact Strap crampon regularly gets good reviews, mainly thanks to its low weight. It also comes fitted with anti-balling plates as standard and these are an elaborate design to improve their resistance to snow balling. You get 10 points, and four of these are rotated through 90 degrees to improve grip on slopes. Some 3D stamping adds to the strength of the crampons too. Adjustment is easy and the crampons can be easily fitted to boots with the straps. Compared to some other models, the price is very good too when you consider what you are getting. These are a very clean design that is easy to use and ideal for general winter walking if weight is your priority, rather than the ability to tackle steep snow slopes all day. But the anti-balling plates are not quite as good as the best here, particularly as a screwdriver is needed to remove them. The spike points are very sharp, so you might snag these quite easily on gaiters before they wear down. As the instructions do not feature diagrams, they aren’t the best for beginners. You are only getting 10 points rather than 12, so grip isn’t the best.
