Groovy Gancini Slide Sandal

I was excited to purchase these slides because I have narrow feet and the width size in the description was B for narrow feet however when I received them the width size in the shoe and on the box was M for medium width. The shoes were too wide for my feet so I called customer service and was told that the shoe only came in B width so I assumed it was a glitch with that pair so I purchased another pair and the same thing M width. The shoe overall was good quality and color but I had to return both pairs.
