Shop-a-holic, shoe-lover needed!!!

Sq
If you LOVE to shop (for yourself and others), are addicted to shoes, and know a good deal when you see one, this post is for you because I need your help!!! Unfortunately, I've run into a dilemma... I was never blessed with the "shopping" gene and I'm in need of a pair of heels. I'll explain: I'm the MOH in my best friend's wedding in March. I need a pair of heels to go with the dress that need to be specifically Colbalt or Royal blue in color. I wear a size 7.5 reg, and would prefer open toe, but it's not a deal breaker for me if they're not. They just need to be comfortable and able to be worn (and danced in) all day/night without killing my feet. I'm not a fan of platform heels or wedges either. I'm on a budget, so was hoping to find a pair under $50 ($50 would be max, but if you can find cheaper that are still good quality, that would be great!) If anyone could help me, I'd be SO GRATEFUL! If you find anything that fits this description, please post a pic and/or link to the webpage so I can buy them! I'm posting a pic of a pair of heels I own that I like to help give you an idea of what my style is, but if you can find a pair that aren't so tall, that would be ok too. Thank you in advance for letting me borrow you as my personal shopper!! Also, if you know any good stores you think might have what I'm looking for that I could physically drive to, that would be great as well, as I'm up for any and all suggestions! Thanks ladies!
