Boots of mobility give only 109 movement speed out of combat
I was playing Yuumi. I bought boots of mobility and when I hovered her movespeed it showed 330+109. (I was out of combat). The boots' tooltip says they give 115 ms.

It's not a bug just a lesser known feature of the league movement system. League has soft caps that if you go over you get less from your move speed items. With Base + Mobility Boots you have 445 raw movespeed which is above the 415 cap but below the 490 cap. This means your move speed is actually (445* .8) + 83, the 439 you see in game.
