The GEL-DS Trainer 19 is a stable yet cushioned lightweight trainer made for fast-paced training and racing. A new engineered mesh upper is lightweight and results in enhanced fit and comfort. Guidance Line combined with a Guidance Trusstic facilitates a more efficient progression from heel strike through to toe off. This is further enhanced by a more flexible forefoot achieved via the implementation of a true Twist GEL unit. Comfort levels have been increased with the addition of a Clutch Counter in the rearfoot whilst Dynamic DuoMax keeps this shoe as supportive as ever.
