I loved my Lowa Vantage boots. Wish they still made them.
When they gave up the waterproof ghost after almost two years, Lowa sent me a brand new pair of boots no questions asked

Sadly they didn't make the Vantage model anymore, and the ones they sent me (I forget the name now) didn't fit my feet as well and lost their waterproofness after about a month

. Not sure what went wrong on those. Being free, I never even tried to take it up with Lowa.
Found a good deal on some Scarpa Zodiacs and HOLY HECK they're amazing. Light, nimble, and tough-as-nails.
Long story short, I still recommend Lowa boots. My lady had some Renegades that served her well for a long time too. They make good stuff.
