I spent hours and hours this season researching to find the perfect equipment. I almost skimped a little on the boots, but I'm extremely glad I didn't. These are the best boots I have ever tried on, and I am extremely picky when it comes to equipment. Inner liner secures tightly, and even has an adjustable strap to hold the tongue back. I started out riding with these boots really tight so that they wouldn't slip. I found out that this is not necessary. My foot has never lifted in these boots, which is very uncommon. The inner liner and BOA system secure these boots great, and the air liner REALLY works amazingly. The air gently holds your heel in the boot, and adds a very custom fit. Durable boot. BOA is a snap, and makes adjusting on the go an absolute blessing. Very easy to get in and out of these boots. BOA may not be that much quicker, but it is much more effective and adjustable by small amounts. With the solid construction, great feel, great looks, and even the option of heated insoles these feature packed boots can't be beat. Spend the extra money and buy these; you won't be sorry. This is one area where you can't afford to skimp.
