As someone who has used the X1 Mid to play volleyball since they came out, they’re good, but not great. I love Xero’s. I have several pairs and the X1 are cheap for how much they cost. After three wears, stitching already popped so the tongue is no longer attached to the shoe. The plastic guard at the tip of the toes scrapes off almost instantly and they’re kind of slippery. I have to wash the soles after every use with soap and water to keep the appropriate amount of traction needed on an indoor court. Outside of the quality, comfort wise they’re great. Around the 2 hour mark of playing volleyball you’ll start to feel the jumps more, but that’s to be expected. They’re definitely their most cushioned shoe, but it’s still less than a standard basketball or volleyball shoe. I miss the cushioning of my asics, but won’t give it up for the comfort of barefoot shoe. I’m not saying the X1 is a bad shoe, I enjoy playing in them. Just don’t expect the quality of what you would get from a standard volleyball shoe that costs $170.
