I usually wear a size 8.5 and bought a size 8 (they didn't sell 8.5 or other half sizes). But as previous reviews suggested their size 8 was a great fit. It's soft, light and keeps its shape. You can almost feel the shoe shrink a little and expand a little as you walk, but it insulates against gravel or rocks on the road or footpath. The grip is better than it looks. Have to see how well it holds up to wear and tear. Update: These shoes are great. The best pair of shoes I've ever had. NOOKNAK team is a great product and great quality. Please keep up the good work
