I'm having some trouble finding a good pair of shoes, too, especially since my right foot is almost an entire size bigger than my left! That makes it so hard, and I almost always come home with one foot in pain! Anyway, here's what Ive learned or experienced, as far as shoes go:
Just last night I ordered a pair of Crocs Professionals online for $34.00--I'll let you know how those are, as soon as I try em. I've heard great things about them. From what I've heard, though, make sure to get the "Professionals" kind, because they have ridges along the sides, to catch any body fluids that might drip onto your feet, so you don't get anything gross falling through the foot vents! They are slip-resistant, although I have heard some nurses say that their hospitals have banned "Crocs" and similar shoes, because people have been slipping in fluids (someone mentioned in another post that this could be due to some less well-crafted knock-offs, which might not actually be slip resistant, giving a bad name for the real shoes).
Here are the other shoes I've tried, though: Dansko--I have had pretty good luck with these. I bought 2 different types, both cost around $100, and one pair has been great (I've had them for over 4 years, and they are still in good shape, except for the fact that the inside of them seems to have become really super smooth, so my feet have started to slide out of them--but that was after 4 years of wear). My other pair of Danskos is not quite as "cushy" inside, but are still very durable and reliable, and are also still in great shape after several years.
Recently, I started having quite a bit of pain at the top of my "bigger" foot, from my big toe up to the front of my ankle, and at first I thought maybe the shoe was too tight, but when I paid more attention, I think it was caused by the inside of my shoe wearing down. I think what was happening was that the new slickness of the inside of the shoe was causing my foot to slide out, so I was "gripping" the inside of my shoe with my big toe, to keep my foot from sliding out. This resulted in the "extensor tendon" (looked it up, cause my foot was hurting so much!!) being stretched an awful lot during my 12-hour shift. That's just my theory, though--I haven't gone to a doctor about it or anything. Has anyone else had this problem, with dorsal foot pain after a long shift, when your shoes are obviously not too tight? This only happens with one of my feet.
I've also worn Nursemate shoes, and those are pretty comfortable, too, and cheaper than Dansko. I've only had one pair, though, and I ended up getting rid of them because the pair I had was just so darn ugly! They do have a huge selection of styles, though. I might try another pair of those if my crocs aren't as great as I've heard they are.
Also, I just ordered a pair of clogs from allheart.com, basically because they were on clearance for $8.99! The sizing system is horrible, though, because I wear a 7.5 (my right foot tends to be an 8, actually, while my left can fit into a 7), and their size small is 6-7 and medium is 8-9--seems like it would be hard to get a good fit with such a wide range. If they hadn't been less than $10, I wouldn't have tried them, but I couldn't pass up the deal. I ordered a medium, and honestly I can't tell if they are too big or not. They are, though, the most lightweight shoe I have ever seen. I am going to wear them for the first time tonight at 1900, so I'll let you know how they are, after my shift tonight!
So, I'll update you when I try the allheart clogs and the crocs! Good luck in your search for the perfect shoe--I know it's a tough one-I'm right there with ya!
