For those 13 hour park days! The axel is a softer option amongst the heavy hitters. This boot will support you through the park and haul ass down the groomer. Sweet spot speed zone lacing lets you customize the fit focusing on heel hold when it matter most. I love this boot, and words cant give it justice. One day in these bad boys will prove you can ride all terrain for days and days and days! It also has heat wiring so you will never be cold again!
