Normally, I can wear my minimus all day long, but this newer version rubs my ankle bone raw.  Had to wear a Band-Aid on it to get through the day.  I really wish New Balance would stick with what works, but they keep changing their shoes year after year.  I guess this works for some, but not for me.  However, it's the closest I can get to what I like.  My previous shoes have zero tread left.
