The Freedom ISO is the first new shoe since Saucony’s EverRun midsole foam began transforming the brand’s running line. The upper is a uniform stretch mesh with the latest version of the ISO fit lacing system, which adjusts the fit with the foot while it moves. With its integrated design, the lacing doesn’t require a cage around the midfoot, so the feel is softer and smoother.
Thanks to its performance and fit, the Zante has amassed a considerable following. The upper fit has been refined with each update, but this season’s is the best yet in adapting to its curvy last. The engineered mesh may be responsible for some of the feel as it holds the foot more supportively.
This update to the Supernova Glide Boost moves the franchise forward to the next generation. This near-complete overhaul adopts features from the entire Boost range. The upper is an engineered bi-layer mesh with stiffer support provided by internally welded layers at the toe. The midfoot has a saddle created by the logo stripes, as before, adjusted to better conform and support.
