I always run in the ASICS Gel 11xx series and happy with them - decided last minute to go for a pair of DS Trainers for a half-marathon tomorrow (a few people have recommended them in the past).
Here's the thing - they felt no lighter than the 1170s so I weighed them on the kitchen scales and they are just 4g (*) lighter per shoe - 328 vs 332.
If there's such little weight advantage should I just stick to my 1170s and take the DS back?
(*) - scales in 2g increments so difference in range 2.1g to 5.9g. Size 44.5 (UK 9.5)
