For decades, the prevailing wisdom in running footwear oscillated between two poles: the natural, minimalist movement and the traditional, moderately cushioned trainer. Then, in the early 2010s, a new silhouette began to appear on trails and roads—clunky, oversized, and defying conventional aesthetics. This was the advent of the maximalist running shoe, a category characterized by exceptionally thick midsoles, often exceeding 40mm in height, designed not for subtle support but for profound cushioning and energy return. More than a fleeting trend, maximalist shoes have sparked a paradigm shift in running culture, driven by a combination of biomechanical promises, technological innovation, and a fundamental rethinking of comfort and performance for the everyday athlete.
The genesis of maximalism is inextricably linked to one brand: Hoka One One. Founded in 2009 by trail runners Nicolas Mermoud and Jean-Luc Diard, Hoka sought to create a shoe that would enhance downhill performance on mountainous terrain. Their insight was radical—instead of minimizing material, they maximized it. The original Hoka designs featured midsoles nearly twice as thick as standard shoes, coupled with pronounced rocker geometries. This “meta-rocker” was crucial; it prevented the feeling of instability associated with such a high stack height by guiding the foot smoothly through the gait cycle from heel strike to toe-off. The goal was not simply softness, but a combination of unparalleled cushioning to reduce impact stress and a propulsive geometry to maintain efficiency. While initially embraced by ultrarunners and those recovering from injuries, the concept quickly escaped its niche.
The technological engine behind the maximalist explosion is advanced midsole foam. Traditional ethylene-vinyl acetate (EVA) foam, while lightweight, tends to compress and lose resilience over time. The rise of proprietary, super-critical foams—like Adidas’s Boost (TPU pellets), Nike’s ZoomX (PEBA-based), and Hoka’s own CMEVA and Profly+ formulations—provided the necessary balance of extreme softness, durability, and energy return. These materials could be deployed in vast quantities without becoming dead weight. They allowed engineers to “tune” different zones of the midsole: softer in the heel for shock absorption, firmer in the forefoot for responsiveness. This marriage of high-volume design and sophisticated chemistry meant maximalist shoes could deliver a unique sensation—a plush, protective ride that still felt lively, often described as “running on clouds” or with a “trampoline effect.”
The primary appeal, and the core of the maximalist philosophy, is injury prevention and comfort for high-mileage runners. The fundamental premise is that by increasing the distance between the foot and the ground, the shoe attenuates a greater percentage of the impact forces that travel up the skeletal system with each stride. For runners prone to stress fractures, shin splints, or joint pain, this can be a game-changer. The shoes also promote stability in an unconventional way. While traditional stability shoes use medial posts to control pronation, many maximalist models employ a wide, forgiving platform—an “active foot frame”—that allows the foot to settle naturally into the midsole, reducing harsh rolling and providing inherent balance. This has made them particularly popular among older runners, heavier athletes, and anyone seeking to extend their running longevity.
However, the rise of maximalism has not been without controversy and biomechanical debate. Critics, often from the minimalist camp, argue that excessive cushioning can create a false sense of security, encouraging heavier, more forceful heel-striking as runners subconsciously trust the shoe to handle the impact. They posit that this can lead to a weakening of the foot’s intrinsic muscles and a disruption of natural proprioceptive feedback—the body’s ability to sense its interaction with the ground. Furthermore, the significant stack height raises the foot’s center of gravity, which could theoretically increase the risk of ankle rolls on uneven surfaces, a concern partially mitigated by the now-common wide base.
The market’s response has been decisive. Maximalism has evolved from a quirky alternative into a dominant segment. Virtually every major running brand now has a maximalist line: Nike with the Invincible series, ASICS with the Gel-Nimbus and Novablast, New Balance with the Fresh Foam More, and Saucony with the Endorphin Shift. The category has also splintered into sub-genres. There are max-cushion daily trainers for easy miles, max-cushion speed shoes with carbon plates for marathon racing (blurring the lines with the “super shoe” revolution), and rugged, maximally cushioned trail shoes for technical terrain. This diversification proves that maximalism is not a monolithic idea but a versatile design principle adaptable to various running needs.
Ultimately, the significance of maximalist running shoes transcends their physical specifications. They represent a democratization of running comfort and a shift in design priorities from “correcting” gait to “protecting” the runner. In a sport with notoriously high injury rates, they offer an accessible tool for managing physical stress. They have enabled countless runners to continue enjoying their passion despite previous limitations, expanding the population of lifelong participants.
The maximalist movement is a testament to the iterative, user-driven nature of running innovation. It emerged from a specific need on alpine trails, was propelled by advancements in material science, and was validated by the lived experience of the broader running community. While not a panacea, and certainly not the optimal choice for every runner or every workout, maximalist shoes have carved out an essential and enduring place in the runner’s quiver. They stand as a bold, cushioned declaration that in the pursuit of miles, comfort and protection can be powerful allies, and that sometimes, more truly is more.
