Hi Jamie,
We have the same situation exactly. We found these perfect "overboots" at Little Mountain outfitters (store in Boulder, CO):

They go over regular shoes like the robeez or really thick socks, and are only $28. We tried boots on our 13 month old and they are just too much for her to walk in. We figured she didn't need something that heavy for the short periods of time she would be in the snow. They are super easy to put on and she walks in them just fine!
Description from website above:
The Molehill Shelled Bootie provides the solution to so many "warm and dry" feet dilemmas for babies and toddlers.
The outer layer is made from a waterproof, breathable Teflon Coated Nylon. The inside is lined with a 17 oz. Non-pill fleece. The updated sole is made from a flexible "rubberized" material that grips well, keeps feet dry and now features a substantial mid-sole for added comfort and durability! They are lightweight, colourful and warm. These wonderful winter booties are VERY easy to put on even the most wiggly of feet, and curled up toes!
Parents use these booties in a number of ways:
1. As the foot covering with the Molehill Snowsuit.
2. As the foot covering when you don't want to use a full snowsuit yet you want warm dry feet for your baby or toddler
3. As a first snowboot. Because these Booties are lightweight, soft and flexible, they are the perfect snowboot for beginning walkers. Just like you use a soft soled shoe, like Robeez.
4. Molehill Shelled Booties worn over wool or fleece socks provide the
ultimate warm and dry combination for those little feet. This combination is the
answer for parents who want their babies in a front carrier or backpack for extended times (for winter hikes, snow shoeing or cross country skiing) or who are living in extreme winter conditions.
