Reception Shoes for bridal party

Hi all! I've been pondering ideas of what to get my bridesmaids for gifts. I'd like to possibly get them fun, cute, and comfortable flats to wear for the reception/dance. Any suggestions as to what brand of shoes are the most comfortable to wear, but yet have a variety of neutral and some fun colors to choose from? A few that I've seen randomly advertised are "Tieks". I'd love to hear input on any brand and even Tieks, if any of you have bought and wore them previously. Thank you so much in advance!
