Navy are for sure nice but I just had zero desire to add the Navys to my UB collection. I had 1.0 Core Blacks but they got totally destroyed/beat. Just bought the 3.0 Core Blacks because I feel that those are still staples to buy before you buy Navy. If you already have Core Black, then by all means get the navy.
Also. Thanks
@BenW23 for the info about sizing on the 3.0s. Since I went TTS 9.5 on the Burgundys, I decided to risk it and buy the 9 in this Core Black. I hope it works out because I could have easily carted and bought the size 9.5 (my true size) but now it's out of stock. Hope I didn't waste my time and have to return these 9s.
