Great product

I have already ran 160 km in them in the fall and winter. I run in the woods, light trail. And they look like a new one. This is the best running shoes in which I have ever ran. For my foot 280mm, I choose 44 size (10UK). Thank you for the great product!

Revolutionary company.

I brought a pair of Stealth 2s last year, i liked them however they were abit flimsy and deteriorated aesthetically pretty quick, These shoes are much more visually appealing and feel great to wear in all conditions, The only thing i would point out about my pair is the tab closure lace system came with a slight defect being the rubber pulley had separated from the laces to leave the string underneath showing. Also there is a final lace loophole on the inside of the shoe digs into my foot when tying the laces tight, however this problem can be easily solved by loosening them. Overall love these shoes and following the progression of this company is brilliant, and they are starting to look better and better, which will definitely attract more interest. next pair i will get is the Magna trails in green when released. P.S weird claim but im sure these shoes have made me more more self aware and confident in myself and my posture, maybe market these positive mental health benefits? Also keep size 13 in stock more, always seems to be the first size to sell out.

Great product!

This is what was missing from my life. Im soo comfortable with the shoe!
