He told WWD: "We did them five times to get them the way she wanted. My workers are the best people. I wouldn't be here without them.
"The shoes arrived the day before and there were too many jewels on the heel because of the long train, so we had women working up until midnight to change it."
Manolo was thrilled with the final look and said Kate, 37, made the ultimate bride.
He revealed: "I've known Kate since she was a little girl. The wedding was divine. Kate has such a presence. You just have to feel it."
Another wedding Manolo enjoyed was the royal nuptials between Prince William and Duchess Catherine, even though he wasn't involved with dressing the beautiful bride.
He said: "I love pomp and circumstance, and I'm very respectful of tradition. Kate and William are great for England. They are so popular, and that will help the country during troubled times. They will bring in a lot of money."
