I had been considering buying a pair of Sidi's for years and never did because of the high price. Once my old Tec 8’s wore out, I finally broke down and got a pair of SRS's. I am amazed at how much better they are. The way these boots grip the frame of my bike is unreal. Once I started riding with these boots, I immediately noticed that I had a lot more control and could ride more aggressively. On the track, I can now catch riders that could just slip away from me before. I would imagine the Alpinestar Tec 10’s offer a similar amount of grip as well as the Sidi crossfire TA’s. The quality of the boots seems to be great also, and I feel I won’t need a pair of boots for a long time. One thing I did notice is that even though they are very comfortable, they are a little snug for the size I ordered, I think someone with wide feet might want a size bigger. I am normally a 10 and a half, so I ordered an 11 and luckily had no problems with fitment, other than being a little on the snug side. Although, as they get more worn in, I have a feeling they will fit perfect. I have noticed the same concerns in other reviews and that was one thing that made it hard for me to order them since my feet are a little on the wide side. Overall though, I say these top of the line boots are where it’s at, if you want good gear that will help improve your speed and control these will definitely help.
