I personally love the Gaerne SG-10's! Awesome protection, very comfortable, top notch buckle system, durable soles, and they seem to last a lot longer than other boots I've had in the past (Tech 8's/Fox Formas). My current pair is 4 years old (riding just about every weekend) and still doing awesome!
Everyone in our riding crew wears the SG-10's and are very happy with them (most everyone switching from other Alpinestars, including a few broken ankles). Plus you might be able to find the SG-10 for under $300 if you look around. Check em out if you get a chance. :cool:
