Cons:I have had the shoes for about a week now. The M65 Pro is a tad small while the Razer Mamba T. The out come is very poor sound quality playback. Dont lock the way I thought they would though. If it weren?t for the insoles sliding I would order one in every color! Now he?s required to wear socks with them and that did the trick. This is my first pair of fitlops to test the comfort and style to price point. Am hopeful that the back strap holds up - doesnt seem as securely attached to the shoe as the other styles, but I REALLY like the adjustability. The design is relatively simple. I have never had this issue with any pair of flip flops in my life.
