I plan on upgrading my touring boots this Spring and am looking at the Vendramini Marathon, REV'IT! Rival, TCX X-5 and Sidi Canyon.
I've been using Prexport's 360WP for the last four years and have been extremely satisfied with their fit and feel, waterproofing and breathability. Their only downside being rather thin velcro tab closures that have, over time, become a bit dogeared.
What do you like or use and why?
