/ Mont Blanc Boots
The other option of course, is to hire a pair of boots.
Bear in mind though, if you have a larger than average foot, a B2 boot will not be as stiff as a similar, but smaller sized boot.
A B2 will last you for a number of years and will do everything you throw at them. Just make sure they are a good fit.
If you don't find anything you like in the uk, one plan might be to buy some out there. Never been to Arolla, but I assume you can hire some for a week, get a feel for the boots, try some on and buy out there. Lots of shops in and around Cham for good choice.
The standard summer alpine b3 you'll see lots of is the sportiva Nepal and Nepal evo. Good if they fit, and probably warm enough unless you suffer badly from cold feet or the weather is unseasonably cold. I prefer the newer type of b3 with integrated gaitor, scarpa phantom or sportiva batura etc. Warmer, lighter, more comfortable in my opinion.
This was taken in the middle of Sept last year - down duvet jackets & goggles all day:
Been up Mt Blanc 3 times over past 20 yrs. Warm B3 boots definitely best . On snow all day & much higher, colder than the 3000m peaks around Arolla. Extra support with your crampons makes it both easier & safer too.
I have a pair of La Sportiva Nepal Evo's to sell, in decent nick with newish soles. Size 8 (euro 42). Sell them for £70 + postage. Probably the most commonly worn boot up the Blanc these days. Mail me if your interested.
For more technical rocky peaks B2 boots are good. Used La Sportiva Trango Evos on Hornli ridge on Matterhorn last year & were v good on the rock but crap on the final icy slope - nil ankle support for the crampon work.
Good luck with your trip.
Just to clarify, everyone speaking about Sportiva Trango boots on here has been talking about the Trango Extremes, which are stiffer and warmer than the Trango S Evo. I use a pair of the Trango S evos for anything requiring a non-technical snow approach, since they are much more packable when on a route wearing rock shoes. However, though it may seem counter intuitive, I actually find the Trango Extreme's better on rock - they seem more precise. If you go for a pair of Trango's, I would recommend the Extremes over the Evos, especially if they are a 'one boot does all' (mont blanc temperatures in mind). Other manufacturers will have similar offerings; get something that fits.
Summer alpine conditions have the potential to be much colder than scottish winter, especially if pushing above 4000m, I would wear B3 unless walking in to a rock route via a glacier.
That said it was minus 25 on our summit day so ordinarliy I might have got away with it but is it worth the risk?
