do (in commandblock)
/give @p minecraft:golden_boots 1 0 {AttributeModifiers:[{AttributeName:"generic.movementSpeed",Name:"generic.movementSpeed",Amount:0.4,Operation:1,UUIDLeast:894654,UUIDMost:2872}],display:{Name:"Speed Boots",Lore:["Put on for a 40% Speed boost!"]}}
1: take the boots twice (two pairs)
2: put one in your hotbar and donot select it yet!
3: put one on your feet...
4: the screen FOV gets bigger
5: without being in your inventory select the boots in your hotbar...
6: now deselect it again and the FOV goes back to normal
7: this should not happen because you still wear your boots!
(
What I expected to happen:
The FOV would not go back to normal and your speed will still be working
What actually happened:
The FOV gets back to normal and lost your speed.
and in a random amount of time it went back to the bigger FOV and the speed effect came back again

Confirmed for 14w03b.

I apologize in advance for my ignorance of how things work around here, as I'm new and I've just signed up.
I was on my 1.8 multiplayer server attempting to create a pair of leather boots that give me ("the wearer") a speed boost of 25% while they're equipped, among other NBT tag-related tomfoolery. However, I have been unable to get them ("the boots") to affect my ("the wearer") speed (nor FOV, for that matter) at all, regardless of whether the item is in my hand, equipped, or both. The command I used is as follows:
/give Sunruine minecraft:leather_boots 1 301 {ench:[{id:2,lvl:4},{id:8,lvl:3}],display:{Name:"ORBIT Runners",color:16384000,Lore:["Light and fast."]},AttributeModifiers:[{AttributeName:"generic.movementSpeed",Name:"generic.movementSpeed",Amount:"25",Operation:1,UUIDMost:44938,UUIDLeast:103883}],Unbreakable:1,HideFlags:7}
My environment is Windows 8.1 Pro, latest version of Java at the time of this post, vanilla 1.8. I hope this is of any help, best of luck to you.
Also, and I'm not sure whether or not if this is related to this particular bug or not, the boots display as the <a href="http://hydra-media.cursecdn.com/minecraft.gamepedia.com/f/f4/Lockedchest13w18b.png?version=00842beccb7f5b7368790e0c653f8d29">purple-and-black checkered block</a> in my inventory rather than as red leather boots like they're supposed to. I have not tested whether this is exclusive to this issue, however.

I just attempted the same /give command that I used in my above comment using a 1.8.1pre-3 client on the same 1.8 server and received the same result.

Confirmed for 16w06a

seems to be fixed in 1.9-pre2
Hmm... This seems like a regression of MC-19275. I'm not sure whether they'd prefer to keep this one open, or reopen MC-19275 and mark this one as a duplicate.
