You're meaning the Hermes Shoes right, which was a bonus that was offered at the start of 1.0's service if you linked your FFXIV account with a current FFXI account? Only if you had that item on your old 1.0 character, you will still have those shoes on your character when you transfer that character into ARR. Eligibility for that item ended a long time ago however, so it's no longer offered, meaning only 1.0 characters which you got that item for will still have it - any new characters you create in ARR will not get Hermes Shoes sadly.

Your 1.0 character will also have everything they had in 1.0 (baring a few exceptions of items that were scrapped in the change over), along with their gil, levels and classes (although again, during 1.0's lifetime there were major changes and the original 'physical level' system was abolished, so any levels you gained with that disappeared, plus if you ever leveled the Sentinel class (SEN), that too was scrapped).

These pages give a list of everything that was removed from 1.0 into ARR.

Welcome back to Eorzea in any event!
