Nike has one of the most confusing running shoe lineups on the market right now. Three Pegasus models. Three Vomero models. Two Structure models. Two racing super shoes. A tempo trainer, a speed racer, and a sprint flat. If you've ever stood in front of a Nike wall and had no idea what separates the Pegasus from the Pegasus Plus from the Pegasus Premium — this guide is for you.

Here's every Nike running shoe in the Cadence catalog, organized by category and explained clearly so you can find the right one for your training.

Understanding Nike's Foam Technology

Before diving into individual shoes, it helps to know what separates Nike's foam types — because they appear across every shoe in the lineup:

ReactX — Nike's standard daily training foam. Durable, responsive, and reliable. The workhorse of the lineup.

ZoomX — Nike's PEBA-based superfoam. Extremely lightweight, high energy return, and bouncy. Used in race shoes and premium trainers.

Air Zoom — Pressurized air units embedded in the midsole. Absorbs impact and snaps back for an energetic, propulsive feel. Often combined with ZoomX.

The further up Nike's lineup you go, the more ZoomX and Air Zoom you get — and the higher the price.

The Pegasus Family — Nike's Everyday Trainer

Nike Pegasus 42 — The Daily Workhorse

The Pegasus is Nike's best-selling shoe and the anchor of the entire lineup. Version 42 adds a new full-length Air Zoom unit — learned from the Pegasus Premium — delivering a smoother, more propulsive ride than before. Over 15% more energy return than version 41, with an increased toe spring for a snappier toe-off. If you want one reliable daily trainer from Nike at a reasonable price, this is the default answer.

Nike Pegasus Plus — The Faster Pegasus

The Pegasus Plus is the successor to the Pegasus Turbo — Nike's ZoomX-powered speed trainer. Unlike the standard Pegasus, the Plus has a full ZoomX midsole with no carbon plate, giving it an energetic, springy feel that's ideal for uptempo miles and moderate speed work. It's lighter and bouncier than the Pegasus 42, but less cushioned for easy day recovery runs. Think of it as your workout day shoe rather than your everyday shoe.

Nike Pegasus Premium — The Luxury Pegasus

The Pegasus Premium stacks ZoomX superfoam on top of ReactX with a first-ever full-length Air Zoom unit — the most cushioned and technically advanced Pegasus ever made. It's designed for long runs and easy days where comfort is the priority. Mixed reviews suggest the ride feels heavy to some runners expecting the snappiness of the ZoomX, but for pure cushioned comfort on longer miles, it delivers. Note: Nike has been offering this at clearance prices recently, so check for deals.

The Vomero Family — Nike's Cushioned Daily Trainer

Nike Vomero 18 — The Plush Daily Trainer

The Vomero is Nike's higher-cushioned alternative to the Pegasus — softer, taller, and more protective underfoot. Version 18 uses a dual-density midsole combining ZoomX for bounce and ReactX for durability, sitting roughly 4mm taller than previous versions. The engineered mesh upper is spacious and breathable. If you want more cushion than the Pegasus without going full superfoam, the Vomero 18 is the answer.

Nike Vomero Plus — The Max Cushion Trainer

The Vomero Plus replaces the Nike Invincible as the max cushion daily trainer in Nike's lineup. Full-length ZoomX superfoam makes it softer, lighter, and more responsive than the Vomero 18, with a smooth rocker shape and a stable base for confident high-mileage running. One known issue: early versions had lace loop durability complaints. If you're buying, check the colorway isn't from early production runs. The ride itself — when the lace loops hold — is exceptional for easy long days.

Nike Vomero Premium — The Super Trainer

The Vomero Premium is Nike's most advanced daily trainer — a gravity-defying max cushion shoe that packs ZoomX superfoam alongside two Air Zoom units (heel and forefoot) for an explosive, snappy takeoff feel in a training shoe. It's wider-based than the Vomero Plus for added stability and features a gentle rocker shape. For runners who want the closest thing to a super shoe feel in a daily trainer, this is it.

The Structure Family — Nike's Stability Shoes

Nike Structure 26 — The Core Stability Trainer

The Structure is Nike's most popular stability shoe. Version 26 uses a full-length ReactX midsole with a midfoot support system that surrounds the arch and an internal support band for a stable platform. The outsole features larger rubber segments for a wider, more inherently stable base. It's a reliable, no-frills stability daily trainer at the same price as the Pegasus 42 — solid value for runners who need guidance.

Nike Structure Plus — Stability Meets Superfoam

The Structure Plus takes the Structure's stability foundation and injects ZoomX superfoam on top of the ReactX carrier layer — the first time Nike has brought superfoam energy to a stability shoe. The result is a bouncy, fun-feeling stability trainer that doesn't sacrifice support. A bucket seat design on the ReactX carrier wraps your foot for guidance, while the ZoomX top layer makes every stride feel more energetic. For overpronators who want more than a standard stability shoe, this is a genuine upgrade.

The Speed & Race Lineup

Nike Zoom Fly 6 — The Carbon Trainer

The Zoom Fly 6 is Nike's carbon-plated workout shoe — more durable and accessible than the Vaporfly, designed for weekly speed sessions rather than race day. Version 6 adds ZoomX foam for more energy return, with a full-length carbon Flyplate for propulsion and an SR-02 EVA carrier for durability. Best for midfoot and forefoot strikers — heel strikers may find it too stiff at slower paces. At $180 it's a solid carbon trainer that doesn't require treating it like a race shoe.

Nike Streakfly 2 — The Short Distance Racer

The Streakfly 2 is Nike's low-profile short-distance racer — inspired by track spikes, built for the road. Version 2 is a massive upgrade, upgrading to PEBA ZoomX superfoam (the same as the Vaporfly) and adding a full-length carbon Flyplate. At 4mm drop it aggressively promotes forefoot running. Reviewers compare it to wearing spikes on the road — lightweight, bouncy, and devastatingly fast for shorter distances. Not designed for marathon distances; at its best from the mile through the 10K.

Nike Vaporfly 4 — The Marathon Racer

The Vaporfly is Nike's most versatile super shoe — the sweet spot between the aggressive Alphafly and the lightweight Streakfly. Version 4 trims foam where it isn't needed to save weight, and increases the angle of the curved carbon Flyplate for more leverage and propulsion. Designed for 10K through marathon distances, it handles a wider range of runners and paces than the Alphafly. For most competitive runners who want one Nike race shoe that does it all, the Vaporfly 4 is the pick.

Nike Alphafly 3 — The Marathon Weapon

The Alphafly 3 is Nike's most advanced racing shoe and one of the most technologically impressive shoes in running. Version 3 adds a continuous bottom layer of ZoomX for the first time — sandwiching the two Air Zoom units and widened carbon Flyplate between layers of foam for smoother transitions and maximum propulsion. The widened base also makes it more accessible to non-elite runners. For marathons and half marathons where you want every possible advantage underfoot, this is the pinnacle of what Nike makes.
