The 21-year-old supermodel - who has been the brand ambassador for the luxury fashion house for over a year - has unveiled her latest creation for the company called the Gigi Boot, which she co-designed, and the star has revealed the shoes were inspired by her hectic lifestyle in New York.

Speaking about her latest venture to Vogue Online, the blonde beauty said: "I was really thinking of myself in New York, running around everywhere during the day and at night."

However the catwalk icon - who has starred in campaigns for designer houses including Tommy Hilfiger, Miu Miu and Balmain - has revealed the footwear range was "harder to execute" than previous clothing lines.

She explained: "I was always able to come up with the look for the shoe in my brain, but they were a bit harder to execute than clothing. These designs have the ability to go from sexy to sporty, and they have an agility to them but a gracefulness at the same time."

However, Gigi was able to put a "unique, personal spin" on the designs because of her "creative vision".

A spokesperson for the label said: "[Gigi was] inspired by the brand's stellar boot reputation, but used her creative vision to put a unique, personal spin on the lace-up bootie silhouette."

The heeled, lace-up combat boot, which comes in a black crocodile-calf leather material as well as gun-metal grey and copper, will see proceeds go towards Pencils of Promise charity to help build three new schools, one in Laos, Guatemala and Ghana.

The accompanying short film for the new garment titled 'Do It Right' was directed by James Franco and sees Gigi take to the ring to box.

However, Gigi has revealed she spent a gruelling "12 hours" in the shoes to shoot the clip, but the 38-year-old actor was "super positive" and supportive throughout the day.

She said: "I boxed for about 12 hours that day. I was obviously so tired toward the end of the shoot, and James was just super positive, and told me to embrace whatever I was feeling at that moment."
