Swap out your crossbars or keep it local and under 50 mph. Though the instructions had graphics too small and there were some poorly drilled holes that made it somewhat difficult to get all the bolts in. I’ve gotten so many compliments on my mic! My toes hit the toe box and my nails aren’t long. Only taking one star off bc my feet are kinda wide and i wish the sole were a bit wider but other wise fit true to my size. but they are nice and light! I bought my first pair about 11 years ago in Walmart of all places. Havent tried the Momentum 3s but after this, I dont feel the need! They fit well and are very comfortable. Best ear plugs I ever bought.
