The Freedom ISO would be the great innovation of Saucony. Always be wary of this kind of message a little rowdy. For general disillusionment is the height of broken promises. Ok, it’s a little cranky old as speech, but the best way to never be disappointed still expect nothing new. Thus, the worse it will be the surprise that will point to the appointment.

At three weeks of the Annecy marathon, so I get this pair of Saucony Freedom ISO, and I must be tempted to set aside pending the resumption. No way to change habits or risk injury so close. It was without counting on the appeal of novelty that always stirs my curiosity.
Finally, Freedom ISO accompanies me throughout the rest of my preparation, and eventually even have my preference to face the 42 km marathon. Back on a beautiful encounter that will not take long to emerge.

First impressions

The least we can say is that the model received to test is the least colorful. Before putting it on, somewhat minimalist shoe in its design is characterized by its lightness immediately (265g in size 44) and flexibility. With a drop announced 4mm, one imagines easily be dealing with a running shoe rather focused competition, quick workouts.

The fit is excellent; the vamp wife breathable stretch meshes perfectly to the shape of the foot. The relatively full lacing helps to strengthen the feeling of being one with the shoe while guaranteeing freedom of movement.

Between the end of the race preparation and I traveled about 250 km on the Freedom on sessions so from 10 to 42 km. What to get a good idea of ​​the characteristics of the beast.

Accustomed to change model regularly, it only takes me a few minutes to tame the Freedom ISO. 4mm drop not asked of particular concern, but indeed, require a little time to adapt to a smooth transition in more runners accustomed to more conventional models. However, the Freedom ISO is not in my view a shoe that could be called minimalist.

While a light and dynamic shoe, Freedom ISO do not forget all the security is in fact what makes the ultimately reasonably accessible and less demanding than other similar models. For the comfort, support and stability are also the appointments. A feat when you consider the difficulty in finding the right mix of all these features.
