Bought to replace my TR7 Saucony black and orange pair.<br />These feel trimmer by a touch, but perhaps because they are new?  Bought the yellow as the orange ones were $20 more for no reason other than the color.<br />Loved my orange TR7s, but these will do.  I have to add that they seem to breathe better than the TR7s.  My feet overheat really quickly and these do such a great job venting that it really is not an issue.
