Lace sock are the new girly thing.

There is something unfashionable about the socks and sandal look but, the socks with heel look works really effectively. I guess it depends on what type of shoe you go for.
The lace sock however remarks to be delicate and makes a shoe more comfortable to wear.
The vintage type of style works best for this type of sock. That's just my opinion. Not dissing the goth/emo lace sock look that can create amazing combinations of clothing.

The whole "socks in sandals" look is seen as a fashion don't, right. Switch the sock to a lace one and you have a very girly look  and can work with a sandal too, just not in a flip flop or on the beach.

If you're a goth, indie kid, vintage etc you can add a lace sock to your everyday look and it will not stick out as if you've added a lace scrunchies to your leg. It will compliment the look. It all depends how many patterns and other lace elements are in the outfit.

I'm always reminded by the childhood white socks with the band of lace on top when I see lace topped socks. Like these:

Then again they are becoming very stylish to wear in a heel shoe. They're pretty for evening decoration in an outfit.         

Pointy Shoe Contortionist act

The pointy shoe trend started by King Henry II ,the king of England in the mid 1100's. He wanted to hide his deformed feet. 

Yes, "deformed" feet. Not everyone else has the pointy foot look. It isn't natural to squeeze your toes into a triangular hole when feet are more of a rounded shape.

In the 80s ladies wore the pointed heels to work. The trend took off causing foot problems such as bunions and crushed toes. To be wearing the shoes all day everyday would take a tole on your feet.

Above link is to a timeline of pointy/high heel shoes.

 It's interesting to think how influential a king or queen can be to fashion. Just because a powerful person  or celerity suites one type of fashion i.e. King Henry II and point shaped shoes, doesn't mean everyone else will also look the best in them. 

Everyone has different shaped feet so would fit different type of shoes. I'd rather protect my feet and wear rounded toe footwear. The very uncomfortable point puts pressure on toes and to me is really unappealing. 

Maybe nearly everyone wears them because magazines like Vogue feature them heavily in issues. Don't they realize how bad they are for your feet?

The left is how a foot is squeezed into a pointed shoe

The pointed stiletto is predominately feminine and boosts confidence. They make a foot appear a different shape. (More thin and longer) Duh! They do make your feet look different shape however, not natural looking and pointy. No normal average foot is triangle. You can easily get the same confidence boost with a rounder fronted heel. Or am I missing a point?   

Not only heels are pointy these days, even flat shoes to boots have a point on the front. Thankfully you can buy footwear with rounded toe part too but, they are less common for heels. That's what I've discovered anyway. You might like the pointy style, but think of your foot health. At least don't go out in them everyday, give your feet a rest from the point style every few days.

I find this trend painful, unnatural, awkward looking, pressure on the toes and ridiculous. Yeah, to me they are ridiculous as the feet get really badly distorted and squeezed when a foot is a precious part of the body that you can't take for granted. 

 Nearly everyone uses THEIR FEET everyday and to put them into gross positions almost like your toes are doing a contortionist act in your shoe, is to me ridiculous.
