The ones above are from Nine West, they have padding on sole and are quite comfortable. As it has black on the shoe I would look at adding some black bracelets to tie it in.
This shoes is from Witchery and is actually rose gold. It would be good for the races.
This is a wittner nude peeptoe, it has a platform under the ball of the food so is more comfortable than a non platform shoe.
This Gladiator sandal form Wittner has a very sturdy heal which will be easy to walk in. It is a style which is very "in" this season.
If you wanted to go high and tonal - this one is stunning on, and you could accessories with black clutch but I would think you feet would be sore by the end of they day.
