I'm afraid none of the search results exactly match your request for a mid-calf chunky heel black boot. However, the "Treaded Block Heel Ankle Boots" for R1199 could work well. While ankle-length rather than mid-calf, these boots have a thick block heel and come in black. The treaded sole will provide sturdy traction and comfort for everyday wear. Let me know if you would like me to search further for a true mid-calf style. As an AI, I don't have access to the full catalog yet, but I'm happy to take another look to find what you need.
