I have no words, amazing shoe, hardness and rebound as they should be. Correct drop, very good support for the foot and personally for me also in the arch. It gives you a feeling that it hugs the sole and provides dynamism in the stride. I believe their sweet spot is at a 4:30-6:00 pace but they also perform well at a 4:00 pace and sprints. Maybe on easy runs below 6:00 they are slightly harder, but the rebound is still there. If you are looking for a cloud-like feeling, it might seem a bit aggressive, but it doesn't demand you to pick up the pace like, for example, a Saucony Speed... Get half a size bigger.

1) Tight fit, get one size bigger.

2) The sole is slightly hard for me.

3) The only negative for me is that it is a very low shoe.

This is my first Hoka that is not true to size. I don't have a wide forefoot but it was so tight there that I had to return them. For the marathon runner I intended them for, it would probably be torture. I will try a size up (42 2/3 -> 43 1/3). Other than that, although I didn't try them on the road, their ride was tightly cushioned with good rebound (suitable for a pace of 5:00" and below). Good mileage.

I am very satisfied with the shoes, I just ran a marathon and my impressions are only positive. I was surprised that my feet did not hurt towards the end (as happened in previous races) but mainly the fact (even though I had worn them on a long run) is that they give you the feeling that you are not running, resulting in you picking up the pace a bit. (We're talking about 5-7 seconds, nothing crazy) Overall, I am impressed. The only thing I am waiting to see is how long they will last.
Update
I wore them in a 75km race and I dare say they did not tire me! I recommend them even for such distances!

Very comfortable shoe for training, without a midsole plate! It gives you the feeling of a high-paced shoe due to the rocker but you can also do relaxed recovery runs!

One of the best shoes in the cushioned performance trainer category, ideal for long runs, tempo, and speed intervals, and at a reasonable price. Lightweight (246 g for size 44), with foam that provides propulsion for easy runs (6:00 min/km) as well as for fast paces (4:30 min/km), with very good performance. Comfortable and easy on the feet up to the half marathon that I have run. Perhaps a bit short in length for the same size compared to other Hoka shoes I had (Mach4, Clifton 6 and 8), but it also comes in a wide version where you don't need to go up a size. Comparing with the Endorphin Speed 3, up to 5:00 min/km I prefer the Hoka, at faster paces the Endorphin performs better.

For the last two years, I have been hooked on Hoka. I just got a pair for my son, and he says the best things about them

Recently I bought the Hoka Mach 6 shoes and they really impressed me. They are very lightweight, I almost don't feel them on my feet when I run. Their sole is very comfortable and provides excellent shock absorption, which helps me run more comfortably and for longer distances. Also, their upper part is made of mesh that allows my feet to breathe, which is very important especially on hot days. Overall, the Hoka Mach 6 are one of the best shoes I have worn and I highly recommend them to those who love running!

Having tried 5, X, and 6, I can say that the 6 is the most soft cushioning shoe among those 3.
