In reply to Davelim8850:
All good points, although the extra weight of the Top Alpine Pro is because of the leather, and not lack of thoughtful design (the Top Extreme Lites are of comparable weight to the Spantiks, and lighter than the Baruntses, and warm enough for Denali, I noticed). If that's what your tropical environment demands, then they're probably just about as good as it'll get!
I live in Spain, and even here it's not easy to find somewhere to try on their high-mountain boots. I'm assured that the fit will be identical to their walking boots, which I've been wearing for years now. And the TOP Alpine Pro has been discontinued, so you'll be lucky to find a pair.
