New Balance Women's Fresh Foam X Hierro V8 Trail Running (Style BW52)

Our review of the New Balance Women's Fresh Foam X Hierro V8 Trail Running Shoe finds it best suited to trail runners and hikers who value plush cushioning and reliable traction on varied terrain. The single biggest reason to buy is the Fresh Foam X midsole with roughly 40% bio-based content, which delivers noticeably softer, longer-lasting cushioning underfoot while also using renewable materials. The shoe blends protective durability from a Vibram Eco-Step Natural Outsole with a breathable upper, making it a comfortable choice for longer miles off-road.

Key Features

• Fresh Foam X midsole: Provides a highly cushioned ride that reduces impact on trails and feels more comfortable on longer runs.
• Bio-based foam content: About 40% of the midsole is made from renewable resources, which lowers the product footprint without sacrificing comfort.
• Vibram Eco-Step Natural Outsole: A durable outsole made from over 90% nonpetroleum ingredients that offers long-lasting wear on rough surfaces.
• Micro-Traction Lug by Vibram: Aggressive lugs improve grip on dirt and rock, helping maintain traction in mixed trail conditions.
• Breathable yet protected upper: The upper balances ventilation with protective overlays to keep feet comfortable while resisting debris intrusion.

Who It's For

The Fresh Foam X Hierro V8 is aimed at women who spend significant time on trails and want a plush, supportive shoe for long runs, fast hikes, or mixed-terrain training. It suits runners who prioritize cushioning and a stable platform over a super minimal, race-day shoe.

Runners who need a very narrow fit or a barefoot-like, highly responsive shoe may prefer lighter, lower-profile trail models. Also, if maximum waterproofing is essential, look to models specifically labeled as waterproof; this Hierro emphasizes breathability with protection rather than full watertight seals.
