I only wore these for 4 hours and was sitting the majority of the time and had a blister on the top of each big toe and the strap around the ankle rubbed my skin raw. I already have this same shoe in British Tan. It is warm without being hot. The last setting is "Side Tone" which is how much of your own voice you hear through your own headset (to prevent shouting). These are great for an inexpensive earbud. You need to basically remove the case from the silicone cover completely to open it, which happens easily because the fit is so loose. It was just in a plastic bag.
