Chukkas with thick soles look great with jeans and chinos. Definitely an alternative from 8" and 10" boots. While Clarks Desert Boots are a go-to for many people when it comes to chukkas, pants with more relaxed fits look better with 'bigger' (not actually bigger size wise, but more robust) shoes. Many thicker chukkas can't be dressed up like desert boots, but do much better come fall and spring weather.
Edit: After scanning lots and lots of chukka boots, I've noticed that most have tasteless branding on the outside of the heel... Oh, well, leave it to branding to ruin a quality product.
