The Gel-DS Trainer 25 is the latest addition to the range and it carries on the tradition of fast running trainers.

The Gel-DS Trainer 25 is the latest addition to range of fast and light racing trainers from ASICS. My first impression out of the box is that they are light, have a nice colour scheme and look they resemble the GS-Trainer 24. The Gel-DS Trainer 25 is available in two colour ways. The men's trainer comes in Black/Metropolis and Fiery Red/White colour ways. The women's trainer comes in Electric Blue/Pure Silver and White/Gun Metal colour ways. I have them in the Black/Metropolis colour way. The trainer is available in the half sizes. I have worn these for shorter distance and training runs and speed work.

The engineered upper is very comfortable and perfectly wraps around the foot. I initially thought that the mesh would stretch a bit but it hasn't and fit snugly. I’m pretty sure that the contoured sockliner helps make the trainer so comfortable. The toe box is generous and allows my wide feet room to spread. I generally wear UK 9.5 and found that these came up slightly generous in terms of sizing.

The FLYTEFOAM™ technology in the midsole provides a snappy and responsive ride. The Rearfoot GEL™ technology gives a good bounce when heel striking. The Propulsion TRUSSTIC SYSTEM™, a moulded component located under the midfoot area, provides stability and helps control twisting and torsion while running. I run on pavements, paths and even cobbled roads so worry about rolling my ankles. I’ve had no issues with stability while putting the Trainer 25 through its paces.

The Super AHAR™ heel plug at the rear of the trainer is designed for durability. The Full Ground Contact outsole and rugged sole provides a great grip on pavements, park paths and roads. The full ground contact design of the outsole formulates a smooth transition from foot strike to toe off.

The Gel-DS Trainer 25 improves on the 24 in terms of comfort, cushioning and responsiveness. They are slightly heavier than the previous addition but there is not a noticeable difference. I’m looking forward to achieving a personal best wearing these. If you are looking for a pair of comfortable and quick trainers then these are great. In summary they look good, feel good and run fast. 


The GEL-DS TRAINER™ 25 running shoe from ASICS is an excellent choice for runners who want to go fast. The shoe helps you achieve those running goals with a great fit around the midfoot and lightweight FLYTEFOAM™ technology ...
