My fiance bought me these to cheer me up (in gray)

I loooove them. Generally, though boots are my most expensive shoe purchase and I buy boots to last for years. So I'm wondering about the wisdom of buying slouch boots. Are they a trend that will be gone by next year or will they be around long enough to make the investment?
