We recommend that you measure your foot length in cm, the foot should be tight in the skate. If the skates lightly squeeze the feet-this is certainly not a problem. The new K2 skates are a semi-finished product. Thanks to the patented K2 Softboot technology, the inner shoe is shaped according to the anatomy of your feet after several uses and it can gain up to 1/2 a size in the heel. Do not order the skates according to the normal size of your shoes, the sizing can be slightly different for every manufacturer.
