Nucleo 2 – Men's – Black/White

 Built for the Long Run

Whether you're logging your first miles or chasing a new PR, the Nucleo 2 is the shoe that meets you where you are and takes you further. Lightweight, fluid, and completely re-engineered from the ground up — this is the neutral trainer that earns its place in your rotation every single day.

At just 9.7 oz, you'll barely notice it on your foot. But you'll feel the difference in every stride.

Anima Midsole Technology Diadora's Anima midsole delivers 30% more responsiveness with 20% less weight — a combination that keeps your legs fresher longer and your runs feeling effortless. Whether you're out for an easy recovery run or pushing through a long training day, the Nucleo 2 cushions and propels in equal measure.

Redesigned for Stability and Control The new asymmetrical midsole geometry isn't just an aesthetic choice — it's functional engineering. Two external excavated zones and a flattened internal construction improve stability and rotation control, while a refined heel-to-medial profile keeps your foot tracking naturally. The heel is 9mm wider, the midfoot 13mm, and the forefoot 5mm — giving you a more planted, confident feel without sacrificing that fluid ride.

An Upper That Stays Put The redesigned tongue is secured laterally with elastic mesh integrated directly into the lining, so it won't twist or shift mid-run. A snug, adaptive fit that moves with you — not against you.

The Details That Matter

• 5mm drop for a natural, low-to-ground feel
• Multi-density DDattivo insole for all-day comfort
• Extended heel outsole rubber (6cm → 11cm on the medial side) for enhanced rotation control
• Perfect for daily training and long-distance neutral runs

Also available in the Nucleo Wide for runners who need a little more room to move.

At Tortoise and Hare Sports, we believe the right shoe is important for foot health. The Nucleo 2 is proof.
