what is the difference between true vs. one size?

The problem here is that the entire web page was clearly written by someone with poor knowledge of English. There are two Delta cleats: red (for free rotation) and black (for fixed position). (Black Deltas will allow free rotation with a few specific models of Shimano-branded Looks from the mid-1990s, but these are very rare today.) There is no "true" or "one size." I don't know what will happen when you order this, since it is gibberish. I'd suggest buying it from someone who speaks a language other than gibberish, so you can tell what you're ordering. Just be sure you need the Delta cleat, not the newer Keo cleat for more recent models (they switched some time after 2005 or so). Most bike shops carry the red Delta cleats and the Keo cleats; black Delta cleats are not common, so you might need to order them online. But don't order from someone who bite the wax tadpole other so many differences become grapefruit. Get it?

I think just one size and it is very large but then I am very small. Wish I could be more help.

They make them in different sizes. I believe medium, large and extra large. When in doubt, order one size bigger. They are wonderful!

I was not sure, so I purchased one large and one extra-large, and both are fine for me.

Use the chart on their site. For a very snug supportive fit (short term workout), go one size smaller.

I would say that a person should definitely use 1 size larger sock is if they are towards the high end normally.The best advice I can give you is to buy socks in both sizes, normal and 1-size up.Don't buy many socks, maybe 2 pair of each size.Try both sizes, and make your normal purchase of the size you prefer.

Nevermind I just saw that they listed it when you go to purchase as one size and 504. I couldn't tell you why they did that. From my understanding these are all the same. They may be referring to an expandable version? I've never seen that before. Wasn't there when I bought mine.

Thought there was one size. I don't recall have the option for different sizes.

I have found that each seller usually offers only one size so read carefully each lisitng before ordering from a seller. That way you are sure you are ordering the correct size.

A little ambiguous, but I believe it means that there is only one size for this model. Which is true.

Hello, I think it depends on how much pressure you want. Obviously the small is going to fit tighter and if you are looking for stronger compression that might serve you better. I personally would choose the small, because the whole point is compression and they do stretch out after awhile so tighter in the beginning isn't necessarily a bad thing.

They actually sell both sizes on Amazon since I bought one of each. Just double check the description before you order because sometimes the photo doesn't match.

This one is 3 and up. I think there are 2 sizes. The cheaper one is smaller.

I BELIEVE that "one size" is 32 oz. Why not just order the 32 oz and be safe? There is only a couple cents difference.

I'm not sure actual measuring makes a difference. They are correct in saying these run small so order the next size up from what you usually wear. They do a terrific job! The only drawback is leaving it on for an excessive number of hours can cause it to start hurting-
