Former United States president and Republican candidate Donald Trump released his line of tennis shoes on Saturday called the "Trump sneakers", NBC reported.

He said, "I've wanted to do this for a long time" at the Sneaker Con in Philadelphia, where he debuted his sneaker brand.

"I think it's going to be a big success because I work with some amazing people who came up with this," he continued.

During the sneaker launch, Trump expressed his interest in connecting with his younger self through the sneaker line. He said, "We're going to turn this country around fast. We’re going to turn it around. And we're going to remember the young people, and we’re going to remember Sneaker Con."

The Trump sneakers feature three different designs of tennis shoes — a pair of high-tops, a pair of red laceless athletic shoes, and a pair of white laceless athletic shoes.

The high-tops, which are gold and emblazoned with a "T" on the outside of each shoe, are called the "never surrender high top sneaker" and are priced at $399 online. The athletic shoes, which feature a "T" and the number 45 on the sides, are priced at $199.

The purchase of a pair of sneakers comes with extra laces and a Trump "superhero charm."

The website selling the sneakers also features a "Victory47" perfume and cologne for sale at $99 each.

The sales of cologne, perfume, and trainers are unrelated to either the Trump Organisation or Trump's presidential campaign. CIC Ventures LLC has been granted a licence to use the former president's name, image, and likeness to market the sneakers.
