The Nike Giannis Immortality 2 is a lightweight, high-performance basketball sneaker designed to match Giannis Antetokounmpo’s fast, powerful playing style. But even the best sneaker won’t perform at its peak if the sizing is off. Whether you’re shopping online or in-store, knowing how this shoe fits can make the difference between a great purchase and sore feet.
In this guide, we’ll break down sizing tips, fit recommendations, and key considerations to help you find the perfect fit for the Giannis Immortality 2.
1. Does the Giannis Immortality 2 Run True to Size?
Yes—but with a slight caveat.
Most wearers report that the Giannis Immortality 2 runs true to size (TTS), especially for those with standard or slightly narrow feet. The forefoot and midfoot areas offer a snug fit to ensure good lockdown during quick cuts and transitions.
However, wide-footed players may experience some tightness, especially in the toe box or medial side. In that case, going up half a size is often recommended for comfort without compromising support.
2. Sizing Tips for Different Foot Types
For Narrow Feet
- Stick with your true Nike size.
- The shoe hugs the foot well and provides excellent lockdown without much break-in time.
For Wide Feet
- Go up half a size to avoid pinching or pressure points.
- If possible, try on in-store or look for retailers with a good return policy.
For Flat Feet
- Consider aftermarket insoles for arch support.
- The Giannis Immortality 2 is more neutral and may not provide enough support on its own for flat arches.
3. Break-In Period: What to Expect
Unlike many performance shoes, the Giannis Immortality 2 has a minimal break-in period. The lightweight mesh upper flexes easily, but:
- Some players note slight pressure around the laces and toe area during the first few wears.
- After 1–2 games or practice sessions, the fit generally becomes more forgiving.
4. Insole and Sock Considerations
Insole Swaps
If you use custom orthotics or want more cushioning:
- The stock insole is removable, making it easy to insert your preferred support system.
- Be aware: adding a thicker insole may make the fit tighter, especially if you didn’t size up.
Sock Choice
Your sock can affect how the shoe fits:
- Thinner performance socks are ideal for a true fit.
- If you wear thicker crew or padded socks, consider sizing up half a size for a more comfortable experience.
5. Youth & Women’s Sizing Advice
The Giannis Immortality 2 is available in men’s sizing, but women and kids can also wear them:
For Women:
- Convert by going 1.5 sizes down from men’s sizing.
- Example: Women’s 9 = Men’s 7.5
For Kids:
- Look for the Immortality 2 GS (Grade School) version.
- Sizing and fit tend to follow standard Nike GS patterns—true to size with moderate toe room.
6. How to Try Them On (or Buy Online Safely)
If trying in-store:
- Wear your usual basketball socks.
- Test the shoe for heel slip, toe room, and lateral support with quick cuts or jumps.
- Ensure there’s about a thumb’s width of space in the toe area.
If buying online:
- Check size charts on Nike or retailer sites.
- Read multiple reviews from people with a similar foot shape.
- Choose sellers with free returns or exchanges in case the fit isn’t ideal.
7. Final Fit Verdict: Who Will Love the Fit?
✅ Perfect for:
- Players with standard or narrow feet
- Guards and wings who want a snug, responsive fit
- Anyone seeking a lightweight, locked-in feel
⚠️ Consider sizing up if:
- You have wide feet
- You prefer roomier toe boxes
- You wear thick socks or need custom insoles
Final Thoughts
Getting the right size in the Giannis Immortality 2 can unlock its full potential—speed, traction, and court feel. While it runs true to size for most players, those with wider feet may benefit from going half a size up. With smart sizing and minimal break-in time, this shoe is a strong contender for players looking for value and performance in one sleek package.
Pro Tip: If in doubt, try them on or order two sizes and return the one that doesn’t feel right. Your feet—and your game—will thank you.
