This is too hard to answer without knowing what size you wear in a specific brand of shoe or, better yet, the brand and the particular last (so that there is some metric with which the EG can be compared). My experience with EG has been that the length runs fairly true to size. I am a US 9 and I wear a 8.5 UK in EG. The only issue I have had with EG is deciding the proper width. Of the lasts that I have owned (202, 606 and 89), the 89 is by far the widest and the longest. Until yesterday, I used to think that the 606 was the second widest. However, I have been communicating with EG the past couple of days and learned that the reason I thought 606 was wider than 202 is that my pair of shoes on the 606 last is the Dover model. That particular style has more room in the instep, which makes it feel like it is wider, even though it is not. According to EG, 202 actually has more room in the toe box than 606. This is consistent with what others have said about their experiences with 202 and 606, and may expain why others thought the 202 was actually less roomy in the toe box (i.e., they were comparing them to the Dover, which is an apples to oranges comparison). If you live in either California or New York, there are a number of stores that you can go to try on some EG styles and learn what size you are. If that is not a possibility, you might try faxing EG an outline of your foot (they are very helpful and are used to receiving a lot of inquiries).
