I hate wearing ill fitted boots, boots that leave you with hot spots, boots that have shoddy quality materials etc.  Zamberlan's are an outstanding footwear manufacturer and have a reputation without equal in the European market.  Until recently, I hadn't had the privilege of owning Zamberlans but now own not only the Latemar but the Tofane as well.  Stitch down is the way to go if you ask me.  I've been in the mountains before, wearing other manufacturers products, limping along with the floppy sole of my boots hangin' down, letting water, snow, dirt, rocks get into the foot well before from "glue on sole" style modern boots and hate it.  I inspect my gear and love to be able to see the stitching, holding fast mile after mile.  I know that the outter sole of the Zamberlan is glued on but the security of the inner sole being firmly attached by at least two rows of stitching is reassuring at the very least.
The finish is top quality, the leather show no wrinkle nor blemish.  The interior leather lining is soft and virtually seam free, or as seam free as can be.  Basically, I love the boot and wouldn't hesitate to purchase another pair tomorrow, or next week, year, decade...but I know with the quality and construction of these boots, I won't have to...These will be around for many years to come.  In point of fact, I'm wearing them at this very moment!

Update!

I am now a forest patrol officer for a local timber company and walk miles per day on my Zamberlans.  They are doing great.  I am heavy, 260 but very nimble for my size :) and my feet take a beating out in the steep slopes of northern CA.  I just replied to an email regarding fit.  This is the gist of what I said....If I were to buy another pair, I'd buy my size.  I have one size that fits exactly what my foot measures to and another one that fits one size larger.  I have to fill the one size larger boot with insoles and such but still get a great boot while the one that was purchased right at my size fits like a glove.  As for the outer leather shell...I have to walk in granite and some lava beds and the outer skin takes a supreme beating.  It shows but, the boot is still living up to it's rugged reputation.  Nothing other than battle scars so far.  No loss of seams, nor breakdown of the boot itself.  Again, I AM HARD ON MY BOOTS.  I hope this helps and hope that you all have a great time in the great outdoors!
