I was glad someone finally brought up socks, thanks Bravery. Good wool or wool blend socks will keep your feet going when you have to bug out. Good padding like gel soles will help with your boot comfort. No matter the reason, you can't go wrong with well made military boots (think what they were designed to do!) or well made hiking boots, you can't go wrong with Columbia, and they have women's sizes. For Men or Ladies, your best size might be in the opposite sex section. A good addition to prepping is steel toed work boots for the work you may have to do. I like crocs as a second set in a bug out bag when you are settled in for a day or need to let your boots dry off. Sportsmansguide.com has good deals on bulk socks, and other things. Go over your route, go hiking, running, trail walking.
