I heard about this company from an interview with a cobbler. He was talking about the same boots I own, Thursday Captains, and mentioned that in his experience this product does a wonderful job. I took the word of a professional and I'm glad I did because this product walks the perfect balance between rejuvenating the leather and putting a great luster on it. It doesn't make them look shiny like plastic, but it gives them a warm/taken care of look(hard to explain) that shows off the nature of the leather.
Originally, USPS lost my package during the holidays, but Thomas from Blackrock gave awesome customer service by sending out a replacement immediately. Blackrock not only supports the quality art of leathercare, but apparently customer service as well. Definitely will buy again from them.
