After much debate, I finally took the plunge! And these shoes are amazing! As a nurse, I'm on my feet constantly and for hours at a time. And the cloudmonsters are literally like walking on clouds. There excellent arch support and my heels have stopped aching. Even the fatigue in my legs have improved. The one concern I have is I don't know how long the shoe will actually hold up over time. I worry that the cushion of the sole will wear out quickly. Other than that I 10/10 recommend!

[Pro]: These shoes are impressively lightweight, incredibly comfortable, and offer fantastic support for running.[Con]: Unfortunately, my experience with these shoes has been quite disappointing. I purchased them just 4 months ago and have been using them only twice a week. However, I've encountered a major issue with the midsole (bottom cushion) which has completely collapsed. The rubber has become partially flattened, rendering the shoes unsuitable for running or walking. Additionally, they now make an annoying squeaky noise due to the uneven surface at the midsole.I own four pairs of On shoes, and while I adore their comfort, it's disheartening to note that all of them have experienced some form of quality issue with just regular use.Regrettably, despite my ... More[Pro]: These shoes are impressively lightweight, incredibly comfortable, and offer fantastic support for running.[Con]: Unfortunately, my experience with these shoes has been quite disappointing.

It's unfortunate to conclude that this brand falls short in terms of quality.On a positive note, I must commend REI for their exceptional return policy and commitment to customer satisfaction, which has allowed me to address this disappointing experience by returning what feels like a "lemon" of a product.

I've been running in my On Cloudmonster shoes for over three months and have genuinely enjoyed racking up my daily miles in them. As you would expect by how they look, they are plush and extremely comfortable to run in. However, with an average of 20 miles of road/sidewalk running per week, I've worn this pair of shoes beyond proper functionality and support. After only three months, the rubber outsole has deteriorated rapidly, while the foam midsole continues to lose its' rebound, leaving the shoes not level in a static state.Being a heavier bodybuilder at 170 lbs, I would attribute the quick wear and tear to my heavy, heel-pounding stride beating down on each shoe with every step. However, one possible design oversight on many On running shoes is the use of ... MoreI've been running in my On Cloudmonster shoes for over three months and have genuinely enjoyed racking up my daily miles in them.

However, one possible design oversight on many On running shoes is the use of relatively thin rubber outsoles (especially compared to equivalent running shoes from Adidas and Hoka). Perhaps if On used thicker, more resilient material for their outsoles, their shoes would last a little longer and rack up more miles before they fail, as all running shoes do.In summary, the On Cloudmonster are stylish and comfortable running shoes that look good, feel good and are bound to make many runners go the extra mile. Unfortunately, for the heavier runners among us, they may not hold up for as much as you'd expect, given their price tag.††For lighter weight runners, your mileage may vary.
