CloudAce Test Run
I was invited for the CloudAce launch/test run in Amsterdam. A very well organised event with a top team of ON experts.
I have used On running shoes (Cloud) since 2014. I have always loved the Cloud - it gives the right balance of cushioning in a very light-weight shoe - ideal for competitions (triathlons, 1/2 marathons etc ...).
In a desperate bid to find some more speed, I have used Nike Vapor Zoom for a couple of races - they are the lightest cushioned running shoe I've ever found and they feel great - but they have a huge cushioned heel and are absolutely the least durable shoe I've ever used. Plus they are expensive. They show significant signs of wear after less than 20 km's and very severe wear after only a couple of 100 km's, but I believe the rate of deterioration diminishes after that and I'll use them til they literally fall apart.
The CloudAce is therefore a completely different type of shoe. It is well cushioned (very well !) and massively more durable, but at the cost of weight (335g) - it isn't as light as the Nike (less than 200g) or the Cloud (230g).
I really enjoyed running in the CloudAce - cushioning was great and they certainly put a spring in your step. Over 5km's the extra weight wasn't noticeable but I wonder if I feel the same ass I try to get back into training for a full marathon.
What I was most impressed with besides the cushioning/comfort is the build quality and robust nature of shoe. I believe these will easily survive the rigours of a long season including winter training.
I'm going to buy a pair for my winter training - a bit of extra weight will mean training harder (ish !) and then switch to the Clouds for pre-race training and races (and possibly use the Nike Vapor Zoom for shorter A-races).
Overall I was extremely impressed wit the cushioning, comfort and quality. Only issue for me would be the weight - but they will be ideal endurance training shoes for me.
