Bounce around with no style? No way. Most bras we tested compromised either support or fashion: The most-structured models looked like 1930s flashbacks, and, while high-tech seamless weaves look great, they lack structure to support larger cup sizes.
The Asics Abby was the exception, combining a compression nylon-Lycra blend with contrasting, wicking, polyester-spandex to win the nod for this season’s all-around favorite. The Abby’s basic racer back offers full coverage, and a split seam reveals a bright, contrasting color and reflective detailing between supportive straps.
The front has a subtle sweetheart V-neck that flatters all bust sizes, and our testers—ranging from A to D cups—said that the bra stayed put despite their best efforts to shake it loose. Contrast stitching in four bright color options means there’s a color for every run of the week. $42; asicsamerica.com
