Hands down the most comfortable trainers I have owned. The foam feels plush on pavement but still snappy when I pick up the pace. Already ordered a second pair.

The knit upper keeps my feet dry through rain and the heel lock is real — zero sliding on my daily commute. True to size, gorgeous olive colourway.

Great grip and build quality. One star off because I wish the white colourway came in more half sizes — other than that, flawless for city wear.
