I had the MT20V1 and they about wore out from just daily walking/work. I like the design better on these as they aren't loud (color) like the original.

Update: 12-13-12 - The shoes have two tears where your foot bends when you walk - on the outsides - DO NOT BUY these shoes. I use them for walking/work and they just tore I am in SHOCK!

Update: 2-21-13 - I contacted NEW BALANCE directly they replaced the shoes FREE OF CHARGE! I did have to mail in the shoes I had originally ordered from Amazon. They did not ask for a receipt or proof of purchase just the BOX and Sneakers. Maybe mine were just defective?

Update: 6-21-13 - Second PAIR started tearing again where the foot bends when you walk - I am done - I own many other NB shoes and these by far the quality is just NOT THERE - DO NOT BUY!!!!!!!
