I already have Scarpa Triolet and Charmoz mountain boots.
Both are sized 43.5 and are perfect.
I have just ordered a pair of Phantom 6000 boots, which I couldn't get in a half size.
I've gone for a 44, only because I know a 43 in Triolet and Charmoz are too small.
Anyone have thoughts on this?

Hello Roy,
I have Phantom 6k's and went a full size up from my street foot. Feeling roomier than my Spantiks in the same size I tweaked them using Superfeet insoles, mid weight wool sock/liner sock combo, and Palau inner boots for a more or less good fit. If they are a bit tight and you have a reputable cobbler nearby you may have the opportunity to get a custom fit boot which is priceless.

Roy,
Not sure if you get this. I'm total newbee . Planing to do guided climb to Kazbek this summer. The club im doing this send me list of items should get . Is this Scarpa 6000 good for elevation 5000m?
Any advice on brands for clothing as this club from europe and all brands they mentioned on list european.
Many thx

Hi Roy-
How did you get along with the size 44?
I'm considering similar so would be interested to hear how this worked out for you.
Thanks.
