This is the third pair of tubes I have purchased from K-Swiss.  I just love them.  They are truly the most comfortable shoes I have ever had.  I wear them all the time, and yes, I have worn through them faster than other shoes, but I know its because I do wear them all the time.  I used to wear Skechers, but now if I try them on, there's no comparison, these are so much better.
And I like the colors and designs.  My last pair was black and lime green, and I loved them too.  I get a lot of compliments on these shoes.  I think they are true to size.
