For years, the Saucony Guide series has had a fairly standard stability shoe design. A medial post or medial plastic piece has been a core part of this series as a medial stability-based shoe. Version 17 is a complete redesign that involved a new geometry both externally and internally without the use of traditional medial-based stability methods. Pulling from current concepts in guidance, Saucony has embraced a new Center Path Technology, which aims to keep the foot and the runners lower extremity moving through a central path unique to the runner. A new maximal geometry adds to the smoothest riding Guide yet, signaling a new era for this series.
