Adidas Ultra Boost 5 GTX Review: A Winter Running Shoe That Actually Keeps Up

Introduction

The Adidas Ultra Boost 5 GTX is a winterized take on the classic Ultra Boost, pairing the familiar Boost midsole with a GORE-TEX upper and a full-length Continental rubber outsole. It is built as an all-weather, all-purpose, rugged trainer that can handle snowy roads, wet tarmac, and daily wear, while still looking sharp enough to double as a travel or casual shoe.

The monochromatic charcoal colorway is a big part of the appeal. It carries a workwear, boot-like aesthetic that looks good anywhere, and dirt does not show easily.

Who This Product Is For

This is a shoe for runners who face genuine winter conditions: snowstorms, wet and icy roads, and early morning miles crunching through powder. If you only occasionally run through rain, the standard Ultra Boost is probably enough, and this version would be overkill.

It also suits runners who want one do-it-all shoe for running, walking, light hiking, and daily use, with more protection and stack than a trail-oriented alternative like the Nike Pegasus Trail 5 GTX.

Main Strengths

The spec sheet is where this shoe earns its keep. Three strong pieces of winter running technology work together: the full-length Boost midsole, the GORE-TEX waterproof upper, and the full-length Continental rubber outsole with an aggressive, almost-lugged tread.

The Continental rubber is a genuine highlight. Grip on wet and snowy roads was fantastic, the outsole really bites, and it does not deaden the bounce of the foam. That is rare for a thicker winter outsole, which can often muck up the ride. What is more, on many Adidas shoes labeled Continental, the rubber is actually a blend or a different compound, but this outsole appears to be full Continental.

The Boost foam itself remains one of the most reliable training foams around. It is not the softest and not the firmest, but it responds at any pace: the harder you push, the more energy you get back. The ride is surprisingly smooth for a 10 mm drop shoe, lively and bouncy, and the tall stack reads at around 45.5 mm measured with the outsole, roughly 40 mm of foam. That puts it firmly in max cushion territory, and the ride feels close to that of the Puma MagMax, though the MagMax has better geometry and a wider base.

Weight is reasonable for what it is: about 320-330 g per shoe, right in line with max cushion trainers like the MagMax at 315.5 g and heavier than the lighter Pegasus Trail 5 GTX. The heel gets a plastic clip that holds the foot securely, which matters on slick terrain.

Things to Consider Before Buying

At $200, this is an expensive shoe, costing more than the Puma MagMax and as much as the Super Blast 2. The GORE-TEX upper also means your feet will heat up in milder conditions, and it adds weight. The outsole adds weight too, and this is not a speed training shoe.

The 10 mm drop may feel too high for some runners, and there is a slightly odd heel cut that pushes the ankle to one side, though that issue also exists on the standard Ultra Boost and tends to disappear once warmed up. Breathability is limited by design.

Buying Advice

If you actually need a specialized winter running tool, there is nothing else with quite the same capability, and this shoe excels at its intended purpose. If you do not, the standard Ultra Boost is the smarter buy, often available on sale for around $100, and it delivers the same energetic, bouncy ride for most conditions.

One tip worth noting: since winter eventually winds down, holding off a month or two could see the price drop as inventory turns over.

Conclusion

The Adidas Ultra Boost 5 GTX turned out to be better than expected, feeling almost like a max cushion shoe rather than just a winterized classic. With a great-looking silhouette, a durable and long-lasting foam that has proven it can go 700 miles, and grip that is effectively undefeated in poor conditions, it is a strong pick if winter running is a real part of your routine. For everyone else, the standard version remains one of the most slept-on training shoes available.
