La Sportiva boot fit?

I'm planning on ordering a pair of the La Sportiva Trango Extremes, and was wondering how they size? I wear a 43 in the Boulder X approach shoe and heard that I should size up to a 44 for the Trango. Anyone else have any experience with this boot? Any help is much appreciated!

The trangos are way more of a narrow toe box. I can't wear them myself, but the Nepals fit work great. For a lighter boot I had to go with the Scarpa Charmoz. And I can wear the Boulder X.

I'd recommmend trying them on first. Sizing up isn't really an answer for a poor fit. You just end up with a sloppy boot.

Yep. Sportivas run narrow. If that doesn't work for you, try Scarpa. Just about as good quality, built for higher volume feet.

I wear a U.S. size 10 1/2 in every shoe or boot I have owned and the size 44 trango extremes fit my foot perfectly. They are the best boot I have ever owned. I use them primarily for ice climbing. When it gets well below zero however they are not warm enough and I use double plastic boots.

This is all really great info. Thanks everybody!

I'm writing this with a 43.5 Boulder X on my right foot and a 44.5 Trango Extreme on my left. I have a little more room in the Trango, but I think that the diffference between a lightweight wool sock (which I wear with the Boulder Xs) and a heavier weight make up the difference between the two fits.

PS - I sized up one size for my Trangos.

I am a 9.5 street shoe and almost ordered a 42.5 in that boot, instead I chose a 43 and they work but a heavy sock makes it a bit snug. If you are near a retailer I would advise trying them on, I didn't have that option living where I do. I might keep my 43 after trying a 43.5 but I would have liked knowing how they compared. I'm thinking the snug fit might make them colder, but so far only one season of ice with them and the temps weren't all that cold . I am however coming off of Koflach's which of course are a double and quite warm. Having said all of the above I think the Trango's are a great boot, really enjoy them. I hope this helps.

Just a thought on sizing and this of course is just my opinion. A good fit in a boot really shouldn't require sizing up, with the exception of the rare times when the manufacturing process doesn't really make it "true to size". Either the boot fits well or doesn't fit. You shouldn't need to wear multiple pairs of heavy socks either, which usually makes your feet colder anyways. I typically wear a thin wicking layer and one heavier sock and it doesn't affect the fit to much in either direction.

Just like with climbing shoes, you can't buy a boot on how awesome it is. Fit is king and will make all the difference on a 15 hour day. Your feet will thank you for the time spent selecting a boot by not giving you heel blisters, sore arches and frozen toes.
