Please can someone help me find a pair of warm winter dog-walking ("low impact activity") leggings. I'm 5'7" and want something that's long enough to cover my ankle. It needs to be a warm outdoor legging not a baselayer that needs another layer on top. I was keen on the Under Armour ColdGear Base 4.0 but the reviews mention that the design has changed for the worse. The Arc'teryx Rho AR Women's Pants should be good at that price, but the Amazon reviews are not impressive. Recommendations please?
