I have 2 pairs of Fly Mistry, and really like them. I need really round toes otherwise my toes are sore by the end of a day walking round London.
They last really well, the other thing to mention is that because they don't have buckles they don't pull the seams down on trousers if you wear them over the top of boots. They also don't have zips all the way up the leg so they don't rip holes in your tights.
I say go for them if you like them and that's a really good price.
Hope that helps
