As mentioned in some of my previous articles on the Hyperfuse (being the original Hyperfuse in 2010, the Rondo PE Hyperfuse 2010, and the Rondo PE Hyperfuse 2010 Low), the upper is made from a fusing of 3 types of materials:
- Stable base layer that acts like a skeleton for the shoe's upper.
- Breathable mesh layer.
- Durable outer skin layer to protect the shoe from scratches and damage.
The midsole is made up of phylon and a Zoom air pocket at the ball of the feet. It is comfortable, and from wearing this, Nike have fixed a minor problem with the 2010 version by making the 2011 Hyperfuse slightly wider. There was a lot of suggestions that the 2010 Hyperfuse was too narrow, and if people were buying it, to go half a size up. I would have to say that everyone's feet are different, and I found that it took about 3 weeks of wearing for the 2010 Hyperfuse to get truly comfortable. There is a less of a wear-in period with the 2011 Hyperfuse, as they feel comfortable immediately.
Other than that, the new 2011 model feels slightly heavier (as I have not weighed it properly on scales), and the upper of the shoe is slightly different. The mesh windows have been rearranged, and there appears to be more arch support on the outside of the shoe. This might be a way to give extra lateral support to what is already provided by the outriggers on each shoe. The traction feels about the same as the previous model.
These shoes were obtained from the Footlocker on Swanston Street, Melbourne, Victoria, Australia.
