Straight on to your feet comfort. There are many ear buds that are much better in this department but these arent unusable. Dog would have been a nice choice as well. Its so snug that I dont even use it any more because it felt like it was crushing the screen in a slow, medieval-torture kind of way. So Ill keep treating it with kid gloves and hope it lasts me for a couple years. While both sole units are the same size, the top of the left is narrower and all askew, giving me sever over-pronation. First time I wore them out, they caused some injuries on both sides of my feet, from the straps rubbing up against them which was painful so be wary of that. I know that for a fact because I bought my other 2 daughters 2 pairs from Nordstrom and those 2 were very different quality than this pair I purchased from Amazon. He loves them and told me last night he plans to wear them all the time. Thank you insta natural!
