adidas Sprintstar Running Spikes Accelerate out of the blocks, then keep the momentum. The Sprintstar Spikes are designed for 100 to 400-metre races. Breathable Mesh Upper Utilising a breathable mesh fabric through the upper of the Sprintstar Spikes, your feet will remain cool and comfortable. The mesh will ensure a constant supply of airflow, to enhance your comfort, keeping you prepared for every mile, and providing you with targeted support. The inner sock and bootie construction will provide you with a sock-like fit, meaning your feet will feel secure and locked down. Using a textile lining, the spikes will also prevent irritation or chafing from occurring, providing you with an optimal level of comfort during your race. Further supplying you with a locked-in feel, these lightweight spikes have a traditional lace closure, allowing you to make preferences for the fit of the shoes. Synthetic Outsole with Spike Plate To provide you with traction and support on the track, the Sprintstars have a spike plate underfoot, alongside a synthetic outsole. This outsole construction will provide you exceptional grip, whilst the sprint spikes bite into the track allowing you to fly on short distances.
