# Collaborative Summer-Ready Hybrid Sandals KEEN Joins Gramicci on the Newport Retro Sandal By Amy Duong | Published 2025-04-24 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/newport-retro References: [keen](http://keen.com)  KEEN works in collaboration with [Gramicci](https://www.trendhunter.com/trends/keen-x-gramicci) as the two drop the Newport Retro sandal -- this marks the second footwear partnership between the two forces. It is partially a water sandal and partially a hiking shoe. Some details include its durable hemp build at the upper and lined with the signature zig-zag mountain stitching by Gramicci. The model is adorned with trail performance elements as it has an adjustable bungee fit and waterproof sensibilities. The Chief Designer at KEEN's Tokyo [Design Center](https://www.trendhunter.com/trends/powerhouse-company), Kohei Yamazaki, noted, “Newport in hemp is a masterpiece that has been released a few times in the past and was a big hit, especially in Japan. It’s even more special now to bring it back with Gramicci as part of their [HEMP](https://www.trendhunter.com/trends/hemp-club-c-revenge-and-beatnik-slide-for-fall) capsule collection. We’re both dipping into our archives, looking back to take a step forward for the planet.” Image Credit: KEEN, Gramicci ## Trend Insights (Trend Hunter) - Score: 5.1/10 - Popularity: 57% | Activity: 56% | Freshness: 39% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: North America, South America, Europe, Asia, Africa ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) ## Key Themes ### Why This Trend Is Growing - **Hybrid Footwear Designs:** The fusion of water sandal and hiking shoe elements showcases a versatile approach to footwear design. - **Eco-friendly Materials in Fashion:** The use of durable hemp in footwear points to a growing trend of incorporating sustainable materials in fashion products. - **Collaborative Capsule Collections:** Collaborations like the KEEN and Gramicci partnership highlight the trend of brands leveraging joint capsule collections to tap into new markets and innovate legacy products. ### Industries Being Reshaped - **Outdoor Footwear Industry:** The introduction of hybrid sandals that cater to both hiking and water activities suggests a new dimension for product offerings in the outdoor footwear market. - **Sustainable Fashion Industry:** Fashion brands focusing on eco-friendly materials such as hemp are reshaping industry standards and consumer expectations around sustainability. - **Collaborative Fashion Industry:** The partnership-driven model in fashion is accelerating the pace of innovation and expanding brand reach through targeted co-designed offerings. ## Related on Trend Hunter - [Hemp Fabric Crafted Sandals](https://www.trendhunter.com/trends/keen-x-gramicci.md) - [Lightweight Marine-Inspired Sandals](https://www.trendhunter.com/trends/hyperport-h2-sandal.md) - [Nostalgic Outdoorsy Footwear](https://www.trendhunter.com/trends/jasper-zionics.md) - [Collaborative Lightweight Bright Sandals](https://www.trendhunter.com/trends/santi-clog.md) - [Collaborative Everyday Shoes](https://www.trendhunter.com/trends/keen-x-pilgrim-surf.md) - [Limited-Edition Urban Sneakers](https://www.trendhunter.com/trends/uneek-sneaker.md) - [Sleek Golf Ready Footwear](https://www.trendhunter.com/trends/keen-x-metalwood.md) - [Roped Collaborative Hybrid Sandals](https://www.trendhunter.com/trends/retropy-sandals.md) - [Outdoor Formal Hybrid Loafers](https://www.trendhunter.com/trends/uneek-loafer-wk.md)
