I got these in Green Synthetic and absolutely love the color.  Nine West shoes are typically a bit narrow for me but I took a chance and got a size 5.  They fit nicely and have a great height, which I was actually surprised to see.  It's been a few years since I've purchased a pair of Nine West pumps and recall only seeing shorter ~3inch heels from them.

These are 4.5 inch heels with about a 0.25 inch platform which is great.  It is so much easier to wear heels with a small platform -- they feel very sturdy and you don't have to worry about feeling every single pebble or piece of debris that may be laying on the ground.

In my opinion they are high enough (and cute enough) to wear out for drinks or to a party, bridal/baby shower, etc., but just the right height to still be considered an acceptable shoe for work.
