Ok, I do bike but I got these primarily as a cold weather running glove that could double for biking.
As a biking glove, they offer no padding (only doubled up layers of the faux leather material in impact areas). As a note, they are also aerated through the underside of the glove, except where the material is doubled up.
All that aside, for my purposes they are great, except they fit really tightly. I got a large (which would be my usual size) and sort of wish I went larger.
First the good things about these: They definitely do the job, they wick sweat so I don't blister, they are really cheap so I don't break the bank, and they are a perfect height so my shoes doesn't rub my achilles.
As a neutral point, they are really thin. This in itself isn't bad, I have other thin running socks I like (but my others are too low, see good points, above) but they feel like you're wearing nylon stockings and they stick to your foot and slip in the shoe.
For the price you're getting a pretty good deal and I'll definitely wear them out, but I wouldn't buy any more.
