Klas & Sylph has three levels of thickness – low, medium, high. The level of our midsole thickness has a direct relationship with the midsole flexibility. While all levels of thickness are flexible, the lower thickness, the higher the flexibility, and vice versa. Nevertheless, higher thickness, though less flexible, comes with greater shock absorption. [...]

A good pair of shoes is the one that allows the feet to move as naturally as possible, especially around the toes that flex the most. Lack or low level of flexibility (i.e. high rigidity) results in high resistance force as you walk, putting enormous strain on the ball muscles as well as Achilles tendon, [...]

It should be fair to say that there’s hardly anyone that stands or walks with perfect balance, putting equal weighting on both sides of the feet. Naturally, we can expect one side of a pair of shoes to flatten more than the other (i.e. unequal flattening), so it is crucial for the footwear midsole to [...]
