I have been able to wear these inside most of my shoes up to 8hrs a day. They are very durable and so soft and comfortable. 10 out of 10!
These are very comfy, although they don't last as long as less comfy toe separators. And they have one other big drawback - the fact that although they appear to come from a company in Kent, individual orders are sent from Australia - hence the rather large p&p costs and time taken to arrive. This seems bad not just from the customer's viewpoint but also in terms of the planet.
Overall the Bunion Sleeve works extremely well. Very comfortable (not bulky in shoe as some Bunion devices are) and very effective in realigning toe comfortably. My main complaint is that as elasticity reduces over time, and the corrective effect reduces as a result, purchasing a replacement fairly regularly at the current price seems expensive.
The bunion sleeves work well and are easy to take on and off, although I find that the size small is a little small for me (it starts to tear near the big toe) and the medium is a bit too loose. I have an Australian shoe size 7 1/2.
I also thought that $35 for one bunion sleeve is quite expensive – I expected to get a pair for that amount.
