When I decided to get the Under Armour Stellar G2, I wanted to make sure I understood everything about this running shoe before making my purchase. Here’s my detailed buying guide based on my experience and research, which I hope will help you too.
Why I Chose Under Armour Stellar G2
The Stellar G2 caught my eye because of its reputation for comfort and support during long runs. I needed a shoe that could handle both speed workouts and daily training without compromising on cushioning or stability.
Fit and Sizing
One of the first things I noticed was the fit. The Stellar G2 runs true to size for me, but if you have wider feet, you might want to consider trying them on first. The shoe offers a snug, locked-in feel thanks to its engineered mesh upper, which adapts well to the shape of my foot.
Cushioning and Comfort
I was impressed with the HOVR cushioning technology used in the Stellar G2. It provides a nice balance of softness and responsiveness, making my runs feel smooth without losing energy return. The foam midsole also adds to the overall comfort, especially on longer distances.
Support and Stability
Because I sometimes struggle with overpronation, I looked closely at the support features. The Stellar G2 offers solid midfoot support and a firm heel counter, which helped me maintain proper form and reduce fatigue during runs.
Durability and Build Quality
After several weeks of use, the shoe’s outsole and upper have held up well. The rubber outsole has good traction on both road and light trails, and the mesh upper remains breathable without signs of wear. This durability was a big plus for me since I log many miles each week.
Style and Design
I also appreciated the sleek design and color options of the Stellar G2. It looks good both on and off the track, which is a nice bonus if you want a versatile shoe.
Price and Value
While the Under Armour Stellar G2 is not the cheapest running shoe out there, I felt the quality and features justified the price. I viewed it as an investment in my running performance and foot health.
Final Thoughts
If you’re looking for a reliable, comfortable running shoe with good cushioning and support, the Under Armour Stellar G2 is definitely worth considering. Just make sure to try them on if you have wider feet, and be ready for a shoe that performs well across various running conditions.
I hope this guide helps you make an informed decision when buying your Under Armour Stellar G2!
