Use -  The Saucony Unleash SD 2 is a performance shoe that’s designed to handle throwing events. These throwing events include the shot put, discus, and hammer throw. This track and field shoe also caters to both glide and rotational movements. 

  • Just like the Asics Throw Pro, the Saucony Unleash SD 2 is a track throwing shoe that is touted to handle it all- whether you utilize a glide or spin technique. Its predecessor, the Unleash SD, has kept a good name in the market. They say that if the componentry yields optimal performance, there is nothing really much to change. The same principle has been incorporated into the design of the Unleash SD 2. 
  • Keeping all critical features of its previous version, this throwing shoe has only gone through one important refinement- the integration of its ISOFIT system. This upper technology allows a sock-like fit to the foot as it conforms to its natural contours.

Providing a sock-like fit to the foot is the Unleash SD 2’s ISOFIT system. It also features a dual lockdown system as it employs a cross strap that is comprised of a Velcro strap that pins the foot down over the footbed. The second lockdown system of the shoe is its lace-up closure system that gives a customizable fit. 

The Saucony Unleash SD 2 is available in unisex sizing, following men’s sizing scheme. It is advised that women go 1.5 sizes down to secure accurate fit and size. 

In order to maintain its durability and deliver a superb surface grip and traction, the Unleash SD 2 features a high-density rubber outsole. This component is also recognized for supplementing a sufficient amount of flexibility, allowing more natural foot movements. 

Situated in the midsole of this track shoe is its compression-molded EVA (CMEVA) midsole that runs full-length. It is an industry-standard foam that provides a lightweight and durable cushioning. Because of the general composition of the CMEVA, a propulsive ride is promoted. 

The integration of the ISOFIT system into the upper of Unleash SD 2 is one of the updates made to it. It consists of a stretchable mesh that wraps around the contours of the foot to give a soft, sock-like fit. 

To further the structural integrity of the shoe, flex film overlays are welded to its upper. These are made up of thin films that secure a snug, lockdown fit. 

In the midfoot of the Unleash SD 2 is a cross strap that consists of a Velcro strap that locks the foot in place. It is intended to heighten the security of the shoe to prevent any slippage or premature removal.
