COMFORTVery comfortable. Clearly states for a 2" square tube and my rack is 2 1/4" These little skinny straps dug into my feet at the wrong angles. Curious as to why a thin blue line and children with a $ are included with this ?black lives matter? set?Just doesn?t sit well with me When I saw this. Very versatile! Ive washed them and sprayed them with Lysol but they still smell foul to the point I dont wear them. I would suggest using some wonder balsam and wearing thick socks a few times before you try to wear these barefoot. Buena calidad volveria a comprar lo. Im sending this crap back and will be buying the 20W USB-C Power Adapter to work with the cord included with the new iPhone.
