Nb; Raidlight Trainers Do Come up Small- We Recommend Ordering Half a Size Larger than Your Normal Shoe Size !! If You Don’t See Your Size or Want Another Raidlight Trainer, Just Message Us and We Will Ensure Our Supplier Has Your Preference in Stock Before You Part with Your Money. Raidlight have developed a wide rounded forefoot allowing the foot to work unrestricted and in comfort. An external heel cradle to support your foot as the fatigue sets in. Highly breathable, quick drying and durable fabrics keep the foot protected and an anatomically shaped tongue ...and cut away heel reduce pressure on nerves and tendons. These trainers are perfect for long distances. Lightweight, breathable, comfortable and technical trainers. The midsole is a full injection moulded system, aiding durability with rebound quality. Long runs will be so comfortable. The rolling sole profile allows a natural transition from heel, midfoot or forefoot strike. These have a 4mm tread depth over the key grip areas, but the sole unit is 50% lighter than a normal sole. With the M-Lock band, this will allow you to have laces under less tension but still maintain foot hold on non technical terrain.
