Very hard to size correctly

I got a pair of the swimruns to replace my VFFs. They look amazing, but were stiffer than I thought they would be. I took them for a short walk to see how they felt and the tab on the back of the heel rubbed the skin off the back of my ankles. The scabs are still healing.

But the package came with a return label so I just popped them back in the package and sent them on their way back. I emailed customer service to let them know and they told me the return policy is a lot more restrictive than I thought (100 day hassle free means you can’t wear your shoes outside the house) so that was surprising to learn. And anyone looking to buy these should probably keep that indoor only in mind.

I’m hoping to get my refund and get a size smaller.

Perfect all around summer shoe

Perfect all around spring / summer shoe. I have been wearing them all the time. I had ordered size 12 but these were definitely too large and have noticed the size 11 is just about right (I normally wear 11.5).

I look forward to my next pear of VIvos. I'm converted to the barefoot shoe lifestyle.
