ASICS Gel Quantum 360 Running Shoes
We engineered the ASICS Gel Quantum 360 for runners who refuse to compromise on cushioning. This groundbreaking trainer wraps your entire foot in our 360-degree Gel technology—delivering shock absorption at every contact point from heel strike through toe-off.
The seamless FluidFit upper adapts to your stride with multi-directional stretch reinforcement, while the Trusstic System reduces weight without sacrificing structural integrity. Whether you’re logging training miles or recovering between hard efforts, the Gel Quantum 360 keeps impact forces away from your joints.
We built this shoe for neutral runners seeking maximum protection on roads and treadmills. The full-length Solyte midsole stays responsive through hundreds of miles, and the dual-density outsole grips wet pavement when conditions deteriorate.
Core technology specs
360-Degree Gel Cushioning Technology
The defining feature of the asics gel quantum 360 eastbay model is the complete Gel cushioning system that encircles your foot. Traditional running shoes place Gel units only in the heel and forefoot, but we wrapped this entire midsole in our proprietary silicone-based polymer.
This means every square inch of your foot receives shock attenuation, not just high-impact zones. The Gel material compresses on impact and instantly returns to shape, dispersing force across a wider surface area. Runners transitioning from minimal shoes often notice the difference within the first mile.
FluidFit Upper and Seamless Comfort
We replaced traditional overlays and stitching with a FluidFit upper that stretches in multiple directions. The engineered mesh base features reinforcement zones that activate under tension, providing support exactly where your foot needs it during the gait cycle.
Instead of irritating seams rubbing against your skin during long runs, the asics gel quantum 360 eastbay uses welded synthetic bands that flex with your foot. The heel counter is molded rather than sewn, eliminating a common blister point. Internal booties hug your midfoot without pressure hotspots.
Sizing, Fit, and Width Options
The Gel Quantum 360 runs true to size for most runners, matching our standard ASICS fit profile. We recommend your usual running shoe size—the FluidFit upper accommodates mild volume changes from foot swelling on longer efforts.
Men’s sizing spans US 6 through 15 in standard D width. If you typically need extra room in the toebox or have higher-volume feet, our 2E (wide) option adds 6mm across the forefoot without altering heel lockdown. The toe box height measures 24mm, leaving clearance for toes to splay naturally.

Gel Quantum 360 Buyer Questions
The Gel Quantum 360 features 360-degree Gel encapsulation around the entire foot, while the Nimbus uses Gel units primarily in the heel and forefoot with FF Blast+ foam filling the gaps. The Quantum provides more uniform cushioning distribution, making it ideal if you need maximum shock absorption across your entire footstrike. The Nimbus feels slightly lighter and more responsive for tempo runs.
Both are excellent neutral trainers, but the asics gel quantum 360 eastbay delivers superior impact protection for heavier runners or those with joint concerns. If you prioritize plush comfort over speed, the Quantum’s complete Gel system offers an advantage during long, slow distance efforts.
Absolutely—the Gel Quantum 360 works beautifully for walking, standing, or casual wear beyond running. The 360-degree cushioning system absorbs impact during heel strikes common in walking gaits, and the supportive upper keeps your foot stable during extended periods on your feet.
Many customers who work in healthcare, retail, or other fields requiring long standing hours choose the Gel Quantum 360 for its all-day comfort. The shoe’s 11.8-ounce weight feels slightly heavier than dedicated walking shoes, but the trade-off in cushioning makes it worthwhile if joint protection is a priority.
The D width is our standard fit, measuring approximately 95mm across the forefoot in a men’s size 9. The 2E (wide) option adds 6mm of width in the toebox and midfoot areas, totaling 101mm at the same size.
If you typically experience pinching across the ball of your foot in standard-width shoes, or if you have bunions or high-volume feet, the 2E provides relief without compromising heel lockdown. The FluidFit upper in both widths stretches to accommodate minor swelling during runs, but structural support stays consistent across width options.
Most runners report 400-500 miles before midsole compression or outsole wear necessitates replacement. The AHAR+ rubber compound in high-wear zones extends durability compared to standard rubber, and the Gel units maintain their shock-absorption properties longer than foam-only midsoles.
Actual lifespan depends on your weight, running form, and surface choices—heavier runners or those who train primarily on abrasive concrete may see closer to 350 miles, while lighter runners on smooth asphalt treadmills can exceed 550 miles. Check the outsole tread depth and midsole compression every 100 miles to monitor wear patterns.
The Gel Quantum 360 is designed specifically for neutral runners with biomechanically efficient gaits. It lacks the medial posting and GuideRails found in ASICS stability models like the Gel Kayano series.
If you overpronate moderately to severely, the neutral platform won’t provide the motion control your gait requires, potentially leading to discomfort or injury. We recommend visiting our men’s shoes collection to explore stability options with structured support features, or consulting with a specialty running store for a gait analysis before purchasing the asics gel quantum 360 eastbay model.
Yes, the factory insoles are removable and can be replaced with custom orthotics. The internal volume accommodates most orthotic profiles without creating excessive tightness, though bulky prescription devices may require ordering a half-size larger to maintain proper fit.
The Solyte midsole and Gel cushioning system continue to function normally with orthotics in place—you’ll still receive the full shock-absorption benefits. Many podiatrists recommend the Gel Quantum 360 as a host shoe for orthotics specifically because the neutral platform doesn’t fight custom motion-control features.
While the Gel Quantum 360 offers excellent cushioning for marathon training, most competitive runners prefer lighter racing flats or carbon-plated super shoes for race day. At 11.8 ounces, the Quantum’s weight and thick stack height sacrifice some ground feel and efficiency that matter when chasing PRs.
That said, many back-of-the-pack marathoners and first-timers prioritize comfort and injury prevention over speed, making the asics gel quantum 360 eastbay a smart race-day choice if you’ve trained in them consistently. The cushioning helps protect joints during the final miles when fatigue sets in and form deteriorates.
