Customer Reviews

Comments: These are by far the most comfortable shorts I've ever run in. All it took was one run after purchase, and now I'm back buying two more.
From: Michael. October 9th 2014

Comments: The previous comments are right on. The Infiniti notch short is the best fitting short I've tried because of the super stretch liner and the cut of the outer shell which is a unique fabric- drapes well with out being clingy. There is a lot of extra stitchwork here to get the fit perfect- the girls will notice! Try one and you'll buy a bunch.
From: Henry, Portland, ME

Comments: These are the best running shorts I've have ever owned, and I've been running for more than a decade.  The outer fabric is very supple and dries very fast while the inner brief is super comfortable (i.e., no chafing or riding up) and not hot in the summer.  The only drawback of this model versus the black is that the black has an inner pocket for a key while the gray pair does not (at least the one they sent me). Excellent shorts. Buy in bulk, and hope Brooks never takes them off the market. (editor's note: The original Brooks Infiniti Notch Short had an internal key pocket. The updated Brooks Infiniti Notch Short II do not have an internal key pocket.)
