It really depends on if you struggle with blisters on your toes or not. I only have one pair and I use them for long runs where I would probably get blisters or hotspots otherwise. It's really too bad they don't sell them in packs though because they're great. For a situation like yours I'd probably get two or three pairs and use them when you feel like giving your feet a break. Sorry this answer is so late... I hope it will be able to help some people out.
