so I cant speak on arch support. It?s so cuuuute! This is my third Tayogo product. Did I mention I have bunions the size of Montana? Yeah, big, painful, knobby bunions from hell. I have had other fleece robes in the past that were very bulky - less desirable. So, I had hoped to use them for 30-45min a day for 3 days/week. One thing I found annoying when I started wearing them is that the sound is not very loud however I realised that in actual fact I had probably had my in-ear headphones at way to high a volume! I am enjoying the phone and its working as I intended. Both pairs basically fell apart with use. I have used this literally EVERY DAY since I bought it.
