I used 2 pairs ISO2, 2 pairs ISO3 and this is my first ISO5. Overall a comfortable fit, with one exception: at ISO5, the front section is too wide for me. The forefoot of my foot is not as protected on the inside as it is on the ISO3. I prefer a slightly tighter fit than a looser fit. Even if this shoe is breathable, it does not tolerate any moisture. If you run a short distance on wet grass, you'll be walking in wet socks for the rest of the workout. I don't know about you, but I have to walk around with wet feet. I think the winter will be bad. I will keep my old ISO3 for winter work or I can just buy another ISO3 before next winter season and keep ISO5 for dry sunny days.
