I am in need of new boots for off road use. I need a boot that offers decent impact protection, that I can move my foot up and down to work the brake lever, but still does not allow my ankle to roll. The vectors are on a good sale. Do they have decent ankle support? The main thing that is holding me back is that I heard they leak like a fish net. Is this true? I am also considering the ARC MX240V. Anyone like these and do they leak bad? I heard some prase for the quadrant. They are a cheap boot and the Thor T30 (or something like that) that I had before were kind of stiff yet not real protective. Are the quadrants a lot better? I tried on some Sidi Raptors and liked them a lot. I can not find any Sidi deals and I don't think they are worth the $200 my local dealer wants for them. My instep is too high for sidi crossfires. I tried the Discovery and could easily roll my ankle in them so they are out. The tech 3 is always another option. Most people seem to like them. I can not try on a pair of vectors so I am not sure what size to get. I wear an 11 in street shoes. I tried on tech 3's in size 11 and they felt good. My local dealer had some tech 7's in size 10 and I found they actually fit. They seemed a bit tight to get fleece socks and seal skins into but I assume they will pack in a little. Anyway, would the Vectors be sized about the same?
