Choosing a snowboard boot can be tricky.  First thing you need to decide is which lacing system you like.  At Milosport, we sell a lot of Traditional laced boots, Boa boots, and the Twin Lacing System or TLS from Nitro.  All of these work really well, and it really comes down to which system you like and which boot fits the best.  There are also some hybrid systems that incorporate traditional systems with Boa or other Quick Lace boots.  Take a look at this video from Jack at Milosport.
