Can I fit into a Proto CTX?

your size sits on the line of choice between wide or not

You may not NEED a wide, but with 11-12's you can justify it and have enough boot to properly engage the edges (as opposed to someone with size 8s where the toe/heel won't even reach the edge). If its a good deal, you will be stoked.

It being a 155 and you being at 175 lbs helps out alot.

This is the exact board I ride at 6' 190lbs and size 12.5 boots. So, with weight you're fine. I agree that you probably don't NEED a wide, but I've found that the CTX is closer to a mid-wide in how it rides. Doesn't feel like a plank at all. I put mine through the ringer (everything but jibbing) and I love it. Has held up great after 75 days or so.

I wear size 11 Burton boots and sold my 158 Proto CTX for a 157 CT... the CT turns so much better and is much quicker edge to edge. I wouldn't go above a 26.0 waist... not sure how the ctx stacks up width wise.

thanks thats what i was looking to hear, i dont want a big fat board feeling all flimsy when im bombing down the hill at high speeds and i like carving alot so being able to do quick maneuver is a plus, i'll stick with reg board
