Don't be fooled by the 90 flex, the K2 SpYne 90 Ski Boot more than holds its own anywhere on the mountain. Think of it as a velvet cougar. OK, maybe the word cougar has too much baggage. Suffice to say the SpYne 90 has plenty of "backbone" and will outperform most of the boots in this category. The 102 last and CushFit INTUITION® liner ensure a comfortable fit from bell to bell, letting you stay out with a smile on your face.
