Sorry. I buy only Cole Haan or Nike, and the shoes I mentioned were purchased about two years ago. As tfar correctly pointed out, the shoes I mentioned are Chelsea's not Chukkas.

They are called the Cole Haan Air Olex Chelsea [also travel occasionally with the Cole Haan Men's Oswego Chelsea Boot or another all black leather Cole Haan Chelsea pair who's model name escapes me]. I have several pairs of the Olex since I 'hoard' size 13s when I can find them. All the Chelsea's I travel with have rubber bottoms, not leather bottoms.
