CSS Float help


I have been struggling with this issue for the last few hours and I can't seem to figure out where the problem is. In all browsers Chrome, Firefox, and Safari desktop this page [url=“urlgone.com - urlgone Resources and Information.”]urlgone.com - urlgone Resources and Information. looks correct but in IE7 the shop by dropdowns are not the same width its like they are cut off. I think it must be a float issue but cant figure it out.[/font][/color][color=#000000][font=Arial,]

Additionally on my iphone the whole mainbox-container everything under Mens Belts is left justified.[/font][/color][color=#000000][font=Arial,]

If someone can help me with what I'm doing wrong here it would be much appreciated.[/font][/color]
