Well, the mixing here is huge. For some reason, those looking for a board think that wide snowboards are not good for them. Only those with big feet need it! Well, that's a big mistake!
Wider snowboards are more stable, you can feel the steep slope better and land much better at the end of a jump. In addition, the same length gives more buoyancy on fresh snow. And they're even a little stronger. With my body weight of 78 kg and my 43 foot, I always prefer the fanned board. What exactly is a widened snowboard?
If the width of a snowboard is over 300m, or it can be recommended for a 46 foot, or the middle width is over 25.8cm, then we can talk about a widened snowboard.
My opinion is that if someone weighs 70 kg and their feet reach size 43, then feel free to choose a wide shoe. This can be marked with XL, WIDE or FT(foot).
However, there are model names where, based on the model name, it is known that they are widened (e.g. Hammer Broadline, SLASH NAHUAL, Burton Bullet)
When is the widened board especially recommended: not for girls, but anyway such boards start at 154cm. Good for people with big feet, heavy weight, strong legs, freeriders, powder snow enthusiasts and candidates for big jumps.
Who should have a narrower snowboard? For those under 42 feet, too light weight boys and girls.
