Rip in my shoe inbetween the sole and the shoe itself , image below

So I’ve got a problem, my very nice Nike trainers now have a rip in them, and I have no idea how to fix them, it between where the sole starts and where the material or the shoe ends. Also there is now a hole in the material on the inside of the shoe just behind that tear so me feet are now exposed. How do I fix this. Image attached
