    Super comfort and my favorite new shoe!

    I decided to order a pair of briefs, more on a whim, because it was getting close to summer, and I had seen people wearing them. I know they had a good reputation, but I was pleasantly surprised to find not only were they well constructed, but they are the most comfortable summer shoes I have had in many years. I will definitely be buying more!

    Super Comfy

    These shoes look and feel great. If I had to pick at them, it would only be that I hate tying shoes…
