The install was slightly tricky but otherwise easy. These shoes are absolutely stunning! The material is like crocs. Since I have to haul 5 bikes, I will keep this one, and place it between the two doubles. I did a lot of research trying to find an upgrade to my touchscreen Id purchased only 2 1/2 months ago (Ankeway) that wasnt over the top in price, had Apple CarPlay, and sounded decent. Ill keep them. These will do the job. There are better subs available for not too much more, from other brands like SVS. I can hear them in our home gym "Ive never felt that part of my back get sore" - giddy as school kids. I love the freedom of not having to carry my phone all the time.
