Barefoot sandals are great for summer time and these can even be worn into the water! They also look good worn with sandals or low cut flats! They're made with embroidery floss or crochet thread, which I know can be intimidating, but I use a size C hook which is larger than what you would normally use for such small thread, and makes it much easier to work with!
