Our goal with our ASICS running shoes is always to enhance the comfort and improve the performance by changing the construction of our styles: adding new materials, new shapes and new performance features.
We have heard that some retailers and consumers are complaining on different sizing problems in Nimbus 19.
Beginning with GEL-Nimbus 19 the materials we are using on linings are little bit different in order to make the step in really comfortable.
What is the consequence?
The foot is forced to move forwards due to additional lining foam. The GEL-Nimbus 19 also has a new last which makes it more toe spring.
This can cause variations in sizing.
For all this reasons in some cases it can help runners to choose half a size bigger vs their regular ASICS shoe size*. Although this is not the case for every single runner it is important to note when purchasing the shoe.
*ASICS South Africa suggests you visit a specialist running store to assess the best sizing for your feet.
