Has anyone come across a great pair of MOTG-worthy booties? I've been searcing for a long time and I'm coming up short. I really want to find a pair or two this fall. My criteria are thtat they need to be comfy and stable enough to wear on sand, wood chips, and wet grass, and they need to not make me topple over when carrying my 23+ lb 9 month old around on my back for an hour or more at a time, while simultaneously chasing my 3 year old--this means heels of pretty much any kind are not an option. No suede--I live in rainy Vancouver. Any suggestions are much appreciated!
Edited to add that by booties, I mean short or ankle boots--just realized I'm not 100% sure that's what "bootie" means.
