I do not have the Pro, but I have owned the Radikal for a couple of years. Warmth is pretty good for a lightweight single boot. The are very comfortable to walk and climb in. I did have an issue with a crack? in the boot last year and on a trip to Colorado this summer, they replaced with a new pair. Boot fits a medium to narrow foot.
Did you find that the BOA system puts pressure on your instep? While it's not the worst fitting boot I have ever worn (the Army does an exceptional job of providing the worst boots ever!) I bought them half a size up (I wear a 10.5 in my Nepal EVOs and bought the Millets in an 11) When I wear a thick sock they seem to do well, likewise when I added an tongue. Just wanted to see if anyone else has experienced a similar fit.
