Nils: Upper could be a bit more breathable (and soft?) Nils / Zack: Guidance groove collects rocks on EVERY run Ryan: Lack of turnover makes this mostly a recovery shoe. Sam: Not as friendly to move along and for heel striking as prior versions. Michael/Sam/ Ryan: Less of a long roll sensation due to the softer foam, more medial support, less outsole coverage Michael / Nils /Sam / Zack: The softer midsole (still not soft!) makes the Shift more versatile towards the slower end of the pace range

Sam: Ride is more fore to mid foot focused with a more aggressive SpeedRoll (also may be a Con for some) Sam: With deep rear medial clip removed stability is moved forward through the side walls geometry Michael / Sam / Zack: More secure upper, especially at the rear Sam / Nils / Zack / Ryan: Still stable and plateless Sam / Nils / Zack: Softer more forgiving midsole foam and some flex unlike earlier Sam / Nils / Ryan: Very light yet substantial on foot It has a new midsole geometry with a more symmetrical rear plastic clip with the heel very deeply embedded in the midsole, a new upper and a thick 7mm PWRRUN+ sockliner join the changes. So what did Saucony have in store for the Shift 3? Well for sure in the trend of the other two it is lighter weight, 0.9 oz / 26g lso ighter than v2 with a slightly higher stack height to a near max “legal” 39mm at the heel with the 4mm drop remaining unchanged. The Speed 3 ( RTR Review ) gets a somewhat broader softer platform which is also more stable leaning it a bit more towards daily training but staying the same in weight, while the Pro ( RTR Review ) jumps up to the max stack height allowable while reducing its weight with a softer ride that broadens its use to more runners and more run uses. With V3 of all three we see quite dramatic evolutions with lighter weights for each. The Shift got an upper update for its v2 as did the other models. And a super successful line it has been for Saucony with focused offerings for different run types all fast, popular and pleasing in their own right.
