Bests & Worsts Reviews from Amazon

I have been wearing this exact style of reef sandals for roughly 5 or 6 years. I have ordered them 3 times from amazon when I decided to see if amazon carried them. I love them, they get used and abused for about 9 months out of the year. So when my old pair was getting pretty worn down I shot off an order for them. Sadly It was December and the period of time where I don't normally get to use them, so I tossed them in my closet for when it gets a little warmer. Today is a nice day so I figure shorts and flips flops is a go. I grab my new reefs and throw them on. I take a few steps and notice i'm sliding around with no traction. I check the bottom to see if something is on them. Nothing there, but it seems like something is different. So I grab my old pair and lo and behold they are drastically different. The bottom is a cheap hard plastic rather than a grippy rubber. It's thinner and the memory foam like material that is so comfortable isn't there. Everything about it screams knock off. However if this isn't the case I will never be buying another pair of Reefs again. I recommended them to everyone. If this is the product they wish to put out now, I can no longer recommend them.
