Kiprun Kipstorm Challenger vs PUMA Deviate Nitro 4

Kiprun's Kipstorm Challenger brings a carbon plate to the more accessible end of the brand's road racing range. Kiprun describes it as a shoe for racing and tempo workouts from 5K to the marathon, developed to target personal bests over the half and full distance and to bring race-day performance to more runners. It is the entry-level alternative to the Kipstorm Elite, and unlike the plate-free Kipstorm Tempo it relies on a plate for propulsion.

The midsole uses Kiprun's VFOAM cushioning, which the brand pairs with the plate to combine what it calls accessible cushioning with plate-driven propulsion. Durable rubber covers the outsole's key wear zones. Kiprun lists it as a neutral shoe without pronation-control technology and says it was co-created with elite athletes and everyday runners. It has an 8 mm drop and a claimed weight of 195 g. See also the carbon-plated running shoes guide.

Positioned as an uptempo performance trainer, the Deviate Nitro 4 is a plated road shoe for interval sessions from mile to half-marathon pace, speed work, long runs and entry-level racing. It replaces the Deviate Nitro 3 and sits between the plateless Deviate Pure Nitro and the race-focused Deviate Nitro Elite 4 in PUMA's Deviate family.

The midsole is built in two layers: NITROFOAM Elite directly underfoot, with standard NITROFOAM beneath a carbon-composite plate. PUMAGRIP rubber covers the outsole, and the breathable, light upper has a padded heel collar and a thin tongue. PUMA has added overall volume compared with the previous version, with more room in the forefoot. The drop is 8 mm. As a plated shoe built for both workouts and long runs, it falls into the super trainer category rather than among dedicated racers.
