I don't buy the minimalist approach to footwear, especially when wearing a pack. This is the minority view here. I prefer a boot that will give me good ankle protection and protect my feet. I wear running shoes most of the time and on day hikes, but not when backpacking. You don't need a full leather boot-those are old school, but I prefer something with at least some ankle support. I badly sprained an ankle years ago while jogging and not being able to walk in the backcountry is potentially a serious problem. Is your BF up to carrying you back to civilization? If not, make sure you have proper footwear.
