In reply to Alpenglow:
I've got quite narrow feet and years ago went for the S Evo as I found these fitted better than the Scarpa Charmoz, which were definitely wider & looser.
I found the only drawback with the S Evos was that they were a bit cold when wearing them in the Alps summer snow. So I replaced the S Evos with a similar boot the Sportiva Trango Alps, which are slightly heavier and slightly more substantial but I've found them perfect for what you're describing - good for scrambling, via ferratas but also a slightly thicker sole than the S Evos, so a bit warmer in snow and hence the UK Winter.
