Runs Large – Consider Sizing down 1-1.5 – Customers noted the Giia sneaker runs slightly large. If you're between sizes, we recommend ordering a one size- half-size down. Break-In Period May Be Needed – Some wearers found the fit snug at first. The materials will soften with wear, offering better comfort over time. Not Designed for Heavy-Duty Use – This sneaker is best for everyday casual wear. It’s fashion-focused and may not offer the arch support needed for extended walking or standing.
