What country do you live in friend where they do shoe repairs? When you say you bought it because its cheap, this is what happens with cheap shoes. I will also admit I buy on the cheap but I am also 100% sure they will not last for 1 year so I can afford to buy a $7 pair of good looking shoes every year. I bought a pair of $60 and they did not last for 18 months so cheap is all I get and throw them away every year.
Your picture does not look like a tear, it looks like a damage from rubbing your shoe on something probably by accident.
