The Nucleo 2 is a cushy lightweight trainer designed for miles on the run. This Diadora trainer features an Anima midsole, which offers 30% more midsole responsiveness while reducing weight by 20%. The Italian design team worked on a new, asymmetrical design of the midsole with two external excavated areas and a flattened internal construction to improved stability and rotation control.

The low 5mm drop and refined upper design make it the perfect companion for long runs and daily training. The upper tongue has been redesigned and is secured laterally with elastic mesh integrated into the lining construction to prevent twisting, ensuring a secure fit without compromising flexibility. 

KEY FEATURES:

• For fluid, long runs: The updated Nucleo has been entirely re-engineered to significantly enhance overall support, while maintaining its reputation as a light, performance-oriented trainer.
• Anima technology: A powerhouse of cushioning, responsiveness and lightness. Anima is Diadora's midsole technology designed to increase responsiveness by 30%, while reducing weight by 20%.
• Centro Ricerche Diadora: The Nucleo 2 was designed and updated in Diadora's Italian CRD, supported by the research carried out with their athletes.
