Victory begins, the moment you want to give up.

You know it. The tipping point. When your legs are burning, your lungs are protesting and that little voice whispers: 'stop'. This is the moment when you almost give up. But you also know: almost is not the same as completely.

Kwakzalver was developed so that you can do one more rep, step or kilometre. With products that remove irritations and obstacles. Read our one more story.

THE STORY OF LUC

What if you almost give up, but still keep going?

Luc ter Haar, marathon skater and co-owner of Kwakzalver, knows how that feels.
In every training, fall and lost match there was always that one moment:
the breaking point. And the choice. Continue or give up.

That's where the idea of ONE MORE was born.
Not as a slogan. But as an attitude to life.
