I have a pair of Montrails in the For Sale section that just might be what you are looking for.
Check it out.
I'm sure others will chime in shortly with their recommendations.
By the way, you didn't mention what kind you currently have or what type feet you have (skinny, wide, short, long, etc).

Boots are a very personal thing and it's best to try on many different styles and brands.
