Miranda Lambert wants you to walk – or dance, or party or sing – in her shoes. Really.

Celebrating the launch of her new Miranda by Miranda Lambert shoe line last week, the singer opened up about the inspiration for her latest project – and her goals for the future – at a party at a DSW store in Frisco, Texas.

“I love projects, clearly,” Lambert, 30, told PEOPLE Country, laughing. “I like to keep my hands in everything. I love it. I think it’s fun. I’ve always wanted to build an empire.”

During the bash, Lambert greeted fans who’d lined up hours before, excited at the chance to meet her – and snack on cupcakes, champagne and punch while shopping.

Lambert, who worked with Rich Footwear Group in St. Louis on the shoes (which retail from $40 to $150), arrived wearing a pair of her own design, the Craig Western Bootie ($69.95).

“They have done such a great job creating this line,” the singer said of Rich Footwear Group. “The shoes are really comfortable and that’s what I love the most.” As for her preferred pair: “It’s hard to pick a favorite – it depends on your mood. Girls tend to dress with their moods.”

The shoes will also be available in Lambert’s Pink Pistol stores in Tishomingo, Okla., where she lives with husband Blake Shelton, 37, and in her hometown of Lindale, Texas.

Lambert came up with the idea to design her own shoes when she couldn’t replace a pair of beloved 1970s-style cowboy boots she’d worn through.

“I thought if I could just get my own boot line, I could make some boots for myself,” she said. “I need them to be sturdy and comfortable for on stage and here it is! It is happening! And it is way more than boots now, there are so many shoes. It is really fun.”
