The world-renowned fishing gear manufacturer "DAIWA". Why did they choose Vibram as their partner for developing the soles, which are the lifeblood of fishing shoes?

DAIWA is a leading company in fishing gear, recently focusing on developing fishing shoes. One of their high-spec models features soles co-developed with Vibram. Shohei Yamazaki, from the Footwear MD department, shared insights on their partnership with Vibram and their approach to product development.

"Shohei Yamazaki is from Yamaguchi Prefecture and graduated from Esperanza Shoe Academy. After gaining experience with designer brands and women's shoe manufacturers, he studied shoemaking in Italy. He joined DAIWA and now works on their footwear department. His passion for fishing began with casting fishing in Shimonoseki during elementary school, and he now enjoys seabass fishing in Tokyo Bay and the Tama River.

ー Can you tell us about DAIWA's history?
Yamazaki: Founded in 1958, DAIWA started with reel development. They created the outspool spinning reel in 1965, which could hold more line and had improved speed and winding capability, shocking anglers worldwide."

"ー Why is DAIWA known for its reels?
Yamazaki: To enhance reel performance, we've focused on developing new materials. In 1979, we were the first to use carbon graphite in reels and rods. In 2007, we introduced "ZAION," a high-density carbon material. In 2010, we developed "Magshield" technology, using magnetic fluid for waterproofing and dustproofing, significantly improving rotation speed and ushering in a new era for reels.

ー Does DAIWA have a long history of making shoes?
Yamazaki: Yes, fishing shoes have been featured in our catalogs since 1975, giving us a history of nearly half a century."

"ー Why did you partner with Vibram for shoe development?
Yamazaki: To achieve the same reliability in fishing shoes as in reels, we turned to Vibram for their renowned grip and toughness in outdoor shoes. Vibram's expertise was a perfect match for our needs."

ー The "FOGLER GORE-TEX" was released last year, correct?
Yamazaki: Yes, it's designed for shore fishing, particularly bass fishing. It features two brand-first specs: a sole co-developed with Vibram using their "Vibram MEGAGRIP" compound and a breathable, waterproof GORE-TEX lining."

Question: What challenges did you face in developing the soles?
Yamazaki: Fishing often involves walking on wet rocks and muddy banks, which are unique outdoor conditions. Vibram's long history and extensive know-how helped us meet these needs."

ー How did the final product perform?
Yamazaki: The grip was impressive, providing stability on unstable terrain. The balance of hardness and flexibility in the "Vibram MEGAGRIP" compound was perfect."

ー What makes the sole design unique?
Yamazaki: The forward-wrapped sole protects the toes, and the spacing between spikes prevents mud from reducing grip. The "Ortholite Insole" offers excellent breathability and durability, with an EVA cup insole for heel support and anti-slip treatment for comfort on sloped banks."

ー What about the GORE-TEX feature?
Yamazaki: The GORE-TEX fabric is shaped into a bag inside the shoe, keeping feet dry and preventing internal moisture buildup."

ー The military-inspired design is also unique...
Yamazaki: We focused on functional beauty, using durable nylon mesh and rubber parts for protection during bushwhacking. The shoes come in three colors: greige, black, and limited gray multi-color, with a subtle brand logo."

ー The shoes don't use traditional laces?
Yamazaki: Correct. We used a speed-fit system to prevent laces from coming undone during bushwhacking, making them ideal for fishing."

ー I think the design makes it suitable for other activities too.
Yamazaki: Thank you. Some staff use this model for everyday wear or hiking. Although currently available only in fishing stores, we're happy to see the user base expanding."

ー The shoes are popular despite being pricey. Why do you think that is?
Yamazaki: The ease of walking with Vibram soles is a major factor. No matter how advanced the upper materials are, the shoe's performance depends on the sole. Vibram's expertise in sole development perfectly met our needs, leading to the creation of the next model, the "Wading Shoes WS-2302C."

DAIWA is a leading fishing brand founded in 1958, known for innovative reels and other fishing-related technologies. They rebranded to Globeride Inc. in 2009 and have expanded into fashion with "DAIWA PIER39" and "DAIWA LIFESTYLE.

Currently, Naoki Ishikawa is on the verge of completing the ascent of all 14 eight-thousand-meter peaks. Why does he choose Vibram as his companion for Himalayan climbing?

ー Since your second Everest summit in 2011, you've visited the Himalayas almost every year, right?
Ishikawa: After my second Himalayan climbing, I summited Manaslu in 2012, Lhotse in 2013, and Makalu in 2014. Spending about two months at high altitudes above 5000 meters changes your diet and breathing. It makes you more conscious of "living," and I enjoy that feeling.

ー When did you start aiming to summit all 14 peaks?
Ishikawa: Initially, I didn't plan to climb all 14 peaks due to the risks. However, as I made more Sherpa friends, they invited me to climb various mountains. Enjoying the climbs with them, I eventually summited 13 peaks.

ー After a break due to the pandemic, you summited several peaks in 2022 and 2023.

Ishikawa: It was easier to climb consecutively while my body was acclimatized to high altitudes. I don't feel it's impressive to summit multiple peaks in a year; it's just practical.

ー Which of the 13 peaks was most memorable?
Ishikawa: Each mountain has unique features and memories. K2 involved avalanches, and Cho Oyu had a whiteout near the summit. Every mountain holds special memories.

ー What about Shishapangma, your 14th peak?
Ishikawa: Although it's the lowest at 8027 meters, it's challenging. The final traverse to the true summit is tough. I attempted it in 2023 but had to retreat due to an avalanche. I'll try again in September-October 2024.

ー Tell us about your Sherpa friends and staff.
Ishikawa: I have many acquaintances in Japan, but a very few true friends. However, I have several Sherpa friends. Spending 1-2 months together, even showing weaknesses, creates a deep connection. They are trustworthy people, even in time of crises.

ー How important is the gear selection?
Ishikawa: Gear selection is crucial for survival, prioritizing functionality. While personal preferences matter, functionality leads to beauty.
ー You've used Vibram for 30 years because you trust it?
Ishikawa: Yes, the yellow mark of Vibram signifies reliability. All 13 peaks I've summited were with Vibram-soled shoes.

ー Any specific experiences with Vibram's performance?
Ishikawa: On K2, I walked over diverse and rough terrain for over a week. Vibram soles provided excellent grip and hardness, preventing injuries.

ー You mentioned using crampons with Vibram soles on Everest.
Ishikawa: Above 5000 meters, glaciers require crampons. Vibram soles are durable, preventing detachment or damage, which is vital for safety.

ー Will you use Vibram shoes for Shishapangma?
Ishikawa: Absolutely. For 8000-meter peaks, Vibram outsoles are the only choice.

ー Have you climbed mountains in Italy, Vibram's country of origin?
Ishikawa: I've climbed several peaks in the Orobie Alps. Italy allows tenting anywhere from dusk to dawn, treating climbers as adults. The Alps have a beautiful scenery, developed hut networks, and active local mountaineering clubs, reflecting Italy's mature mountain culture.

ー Do you have any plans after completing the 14 peaks?
Ishikawa: I have a large solo exhibition planned in about two years, focusing on photographing Japan's peninsulas like Shiretoko and Noto, re-examining Japan from the sea.

We wish you success in summiting Shishapangma this fall and look forward to your exhibition. Thank you for your time.
