Absolute satisfactionThe online ordering process was quick and easy. I really thought payment would be a hassle but that happened faster than I could have any second thoughts... In the end having second thoughts would have been a waste anyway because the product I ordered got to me very quickly, and is absolutely perfect-worth the money I paid for it. Enquiries made during the process were handled speedily and courteously. I'm very impressed.

Great Clogs but too small for me.Clogs arrived very quickly and were well made and looked super. Problem was the size. They were supposedly a mens 12, but were more like an 11 as my heels were right on the back edge. Asked for a bigger size but they do not do it bigger. Had to get my money back. Gutted, as needed them for holiday!!!
