I like a minimalist shoe with plenty of grip - nothing like a slippy surface or wet metal to practice your ballet moves! These are an excellent option. I have just over 100 winter miles in them so far, and LOVE them. Good, comfy fit, box is comfortable and the undersole very comfortable. Grip is outstanding, tested on smooth pavement, small and large gravel, muddy surfaces, rain and ice. Nice padding to the heel, and I feel slightly higher than other shoes - welcome for extra heel protection. I especially like the full length tread, which means the whole shoe has a good grip when walking, obviously less so when running (unless you have flat feet). Overall, great fit (I am a 10, bought 10.5), VERY comfortable, fantastic grip, reliable and I expect to obtain hundreds of miles from them - I run around 40 miles a week, plus races including trail/road marathons. I have no hesitation in recommending these shoes for both trail and road - they are an ideal crossover and great minimalist option in all weathers.These are very comfortable and fit my feet like a glove, but the simple fact is that when I use them for running I seem to feel more pains and niggles and, perhaps coincidentally, have had more back/leg problems since I bought them than in recent times. I have bought loads of ASICS shoes over the years and this is the first time I had that feeling. Maybe it's a heel drop thing.Incredibly comfy and understated styleGood quality and very comfortableBought for hubby and he was so happy with those shoes
