Understanding flex

Soft or stiff – what flex means

Flex describes how much force it takes to bend the cuff forward. The higher the number, the stiffer the boot and the more direct the power transfer – good for sporty and heavier skiers. A lower flex gives more and skis more comfortably.

Ganador 120

„Many thanks for the expert and really great advice on our new AquaNovoBoot ski boots. For us they are the best ski boots there are.“

Alexander G.Google review, January 2023 · translated from German
El Mastín 140

„At first I was very sceptical, because my left leg is badly swollen due to an illness, so I don’t fit into a normal ski boot. […] After just two hours I had my new ski boots with a perfect fit.“
