You want a leather midsole even if the outsole isn't, and the fact that they called it "manmade" means it's probably not rubber, and definitely not vibram or another reputable outsole manufacturer.
Picture of the sole.
They seem to be decent quality.
Count the stitches between the welt (between the boot and the sole) and count the stitches on the sole in the same area.
If they don't match, then you've done fucked up and wasted your money
