These are my first try with chukkas and I have to admit they are wonderful and comfortable. A light color suede is also another first. I got these because it was too good to pass up from fleabay. So, I can't really comment on St. Crispin's pricing not on a first hand experience.
I think I will definitely try chukkas in the future. My right foot tends to have a higher instep than my left, but I also have very low arches.
