New Balance DynaSoft Nergize Sport V2 Cross Trainer (Style SD8K)

Our review of the New Balance DynaSoft Nergize Sport V2 finds a shoe built for everyday training and casual wear, best suited to runners and gym-goers who prioritize cushioning and lightweight performance. The single biggest reason to buy is the DynaSoft midsole, which blends responsive energy return with plush comfort for long sessions on feet. While not perfect for heavy-duty use, these trainers deliver a locked-in fit and stylish look that work well for short runs, fitness classes, and all-day walking.

Key Features

• DynaSoft midsole: Provides a balance of soft cushioning and responsive rebound to reduce fatigue during runs or workouts.
• No-sew upper construction: Offers a sleek, streamlined fit with fewer pressure points and minimal seams rubbing the foot.
• Synthetic and textile upper: Keeps the shoe lightweight and breathable while maintaining structure for support.
• Durable rubber outsole: Delivers reliable traction on gym floors and pavement for everyday training use.
• Adjustable lace closure: Allows a customizable, locked-in fit that adapts to different foot shapes and activities.

Who It's For

These cross trainers are aimed at women who want a versatile shoe for light to moderate training, including treadmill runs, studio classes, and active days that involve a lot of walking. The combination of comfort and lightweight construction makes them a strong choice for people who prioritize cushioning without excess bulk.

Shoppers seeking a heavy-duty trainer for intense trail running or high-mileage daily pounding should look elsewhere, as some customer feedback raises concerns about long-term durability and tear under intensive use. Also, buyers who need a very precise fit may want to try them on first, since sizing reports are mixed.
