I'm a women's size 5 so a boy's 3.5 or 4 will fit. I ordered a 3.5 and they fit great with or without socks. The color I ordered was the original Sahara color. I didn't give them 5 stars because the shoes look like they are a bit poorly made. They look like the original Sahara shoes I saw at Macy's but they are not 100% well made. But overall I'm happy with them because they're about $20 less than in store and they don't look that bad.
