Ho il 43 (Nike) e la misura 42/43 calza giustaConsigliate 5M, a half size smaller than my usual size 8. I usually wear size 4 in Crocs, but since reviews mentioned this style being a bit narrow, I ordered size 5 instead. These refurbished XM4s are the real deal. This works great as it securely holds the trimmer and is light weight and portable. Super Cute! Pros-Excellent sound, i use them for a variety of games from Call of Duty to Sea of Thieves, and the sound is great. The strip should come pre-bored with three holes to match the holes in the mounting bases, and thus provide ten times the break resistance of the bases should a wind or other force attempt to lift the rack load off the roof (& perhaps onto the road or into another vehicle. Ive got more photos than Amazon will probably allow, but Ill try to add a few for illustration purposes. They work well enough while Im on the job but theres too much bass not enough highs and Im lucky if I get 2 hours worth of constant full power.
