These are the new Asics 33 DFA running trainers.
Weighing in at 250g it boasts a 4mm drop, making it a real lightweight and natural running trainer.
The top layer is a natural foam to provide more cushioning and an extra spring and bounce in your step.
It has a fluid axis on the bottom and a forefoot groove, which allows a lot of flexibility and robustness. This gives the name DFA – Deep Fluid Axis. It means that your feet will feel even better when running on a tough terrain or over long distances.
It’s not available until January 2015 and will retail at £90.
