Straightening Toes

I have slightly crooked toes on both feet which I think is because of the shoes I’ve been wearing most of my life.
I also have corns on both big toes and on my right foot I have two cyst-like lumps.
I am planning on buying larger shoes soon with more toe room, but I would also like to try out one or two of the toe straighteners I’ve found on the Internet.
Here are two sites:http://www.footsmart.com/ProductRecords.aspx?category=BT&pgtitle=Toe%20Straightener&srccode=IGKS357Hhttp://www.myfootshop.com/detail.asp?ProductID=706My questions are: 1) Do these toe straighteners actually work and if so how long will they take to work?
2) Since all of my toes are crooked in one way or another, which straightener would work the best?
3) In regards to the cyst-like bumps on my feet, what might the actual cause and cure be for this?
Thanks so much!
