First - I LOVE your avatar picture. That is adorable
.
Sorry to hear about your foot. Without a swimming pool, I guess biking would be the next best thing. You'll probably just have to try it & see how it feels. In the end, taking a few days of full rest may be best. How about looking into some pilates videos? Generally all mat work, so no pressure on your feet at all. Otherwise, maybe some gentle walking to warm up & focus on strength trianing until your foot is better?
I don't know - just don't push it in case your injury gets worse.
I hope you heal up quickly.
