Translation:Mis zapatos son nuevos.
The given answer is OK, but the advice below is "pay attention to the gender". Well, the gender was not the problem, my answer was in singular when plural was correct. But that's not the gender.
I guess since shoes are two, that's why it's nuevo"s"? I thought since they're a pair, it would be singular. Is that true for other pairs too? Pair of jeans, pair of glasses, pair of earrings, socks etc.?
