Kendall and Kylie Jenner on Collaborating With Steve Madden: "It Was Amazing"—Watch Now!

Plus, hear Kylie gush about Kanye West's work ethic

Kendall and Kylie Jenner continue to make an impression in the fashion world, and now they've released their own handbag and shoe line with Steve Madden.

The brunette beauties tell E! News that venturing away from clothes for a bit to focus on a shoe collection for Madden Girl only made sense. "I think with our clothing line, we had so much fun doing that, so that led into the next step which was shoes," Kendall tells us while she and her sister were at Nordstrom at the Americana at Brand in Glendale, Calif., for a meet-and-greet with fans.

Kylie adds, "We grew up with Steve Madden and I remember buying my first pair of Steve Madden boots, and everyone in my school wore them. It's just such a great collaboration."

Kendall continues, "We were really involved. I think we wanted to be really involved and literally sent inspiration to everyone at Steve Madden and they made it come to life. It was amazing. They're amazing to work with because they really did take our vision and put it on to paper and then eventually a product."

Additionally, Kylie says that she was especially inspired by her roommate Kanye West, whose work ethic and passion she praised.

"He's really inspiring just watching him. He's been my roommate for a couple months now, so just watching him," she tells E! News. "He's so passionate about his stuff and he's very, very into it, so it's just awesome to see that. He's just really excited about it. He's always showing me his designs. He's such a creative guy. He's awesome and has a lot of talent so it's cool to see that. It's inspiring. It makes me wanna work harder."
