diadora NUCLEO 2 GR – Built for Every Surface. Ready for Every Run.

The Nucleo Line, Evolved for Mixed Terrain.

Nucleo 2 GR is the evolution of the Nucleo line — made for those who run daily across a mix of surfaces. Everything that made the Nucleo 2 a foundational daily trainer has been retained and reinforced with a purpose-built GR outsole for runners who refuse to stay on one surface.

Engineered for Gravel and Mixed Terrain

The specially designed GR outsole is built for durability and high performance on gravel, grass, and delivers even greater comfort on asphalt. The tread pattern offers superior grip without being so deep that stones or debris become embedded — a deliberate balance between off-road capability and on-road feel.

ANIMA: Responsiveness Meets Lightness

The ANIMA midsole delivers 30% more responsiveness and 20% less weight versus standard EVA — ensuring a smooth, fluid ride for runners of all levels, whatever the terrain underfoot. Weighing just 320g (US size 9), Nucleo 2 GR moves with you, not against you.

Stability and Rotation Control

The asymmetrical midsole design features two external excavated areas and a flattened internal construction — improving stability and rotation control across uneven surfaces. The medial heel rubber coverage has been extended from 6cm to 11cm for superior torsional support where it matters most.

Precision Fit, Wider Base

The upper tongue has been redesigned and secured laterally with elastic mesh integrated into the lining — eliminating twisting and bunching mid-run. The fit geometry has been widened across the entire foot: +9mm heel, +13mm midfoot, +5mm forefoot for a locked-in feel without restriction.

Who It's For

• ✓ Runners who mix gravel, grass, light trails, and asphalt in the same session
• ✓ Neutral runners seeking a low-drop, natural stride on varied terrain
• ✓ Those who want the feel of a road shoe with the grip of a trail-capable outsole

Surface: Gravel, Grass, Light Trail, Asphalt. Not intended for technical trails or heavy mud.
