I bought it on Amazon. The first time I wore mine. It is very easy to install even though first time. I wear them 10 to 12 hours a day very well so far. The plain velcro ones I have are no longer efficient because the velcro lost its strength. The phone fits easily with or without the case on. MicIve had people in Discord and now Twitch chat tell me my mic is incredible. Thus essentially the shoe begins to fall off while I am walking around my house. For you can only kill a person but not the words of his mouth nor his deeds. This is one of the shoes approved by the studio.
