Each sport rubs in different places
Marathon & Road
Many half marathons and marathons are spoiled by blisters, chafing and raw nipples, not by fitness.
Peak race seasons in the US: March to May and September to November.
Shop Marathon & Road →Trail & Ultra
On trails your feet get wet, sandy and hot for hours, and the descents push toes into the front of the shoe.
Peak season in the US: April to October.
Shop Trail & Ultra →Fitness Racing
Fitness races combine running with functional workout stations: sled pushes and pulls, rowing, carries, lunges, burpees and wall balls.
Indoor events run all year.
Shop Fitness Racing →Triathlon
Triathlon stacks three kinds of friction: the wetsuit collar on your neck, the saddle and tri suit on the bike, and wet feet straight into running shoes, often without socks.
Peak season in the US: April to October.
Shop Triathlon →Obstacle Racing
Obstacle course races mix trail running with walls, rigs, monkey bars, rope climbs, crawls and mud.
Peak season in the US: May to October.
Shop Obstacle Racing →Ski & Snow
Stiff ski and snowboard boots press on the same spots all day: the heel, the ankle bones and the shin.
Season: December to March. More ski-specific products are coming for the 2027–28 season.
