Hi! I'm going on a work ski trip to Austria in March. I don't really want to take up many pairs of shoes but I want something that's waterproof and warm yet still "stylish" enough for dinners and possibly using them even after the trip. Most of the waterproof boots I found online are very bulky and I doubt I'd ever wear them again after my 4 day trip. Also, they must be warm!!! I'm from Malta and we're definitely not accustomed to any temperatures below 10 degrees. Any suggestions?!
