How do I help my dog enjoy walks more?

I take my 7 month old pom/chi cross out daily, weather permitting, but she just doesn't seem to like it much most of the time. She's long haired, and I don't take her out when it's cold or rainy or dark (she uses pads), so I don't think she's uncomfortable. I use a buddy belt harness with soft liners so she isn't getting her throat pulled or anything. She even has soft leather memory foam shoes so her pads aren't getting scratched up. She's used to waking on a leash and in shoes-she's fine with it all inside. And she has tons of energy-she'll zoom around the house like a madwoman . But outside she just snuffles around a little and wants to be carried lol. I don't understand it-I mean granted she didn't start going out for a long time between waiting until she'd had her last puppy shot + 3 weeks (per vet instruction) and waiting until it was warm enough tha she didn't just shake and cry, but most dogs love going out. How can I show her it's OK? She even seems to WANT to go out but once she's actually out just isn't into it
