When a paladin wears and activates boots of speed, can he use share spells so that he and his mount are hasted ?

Nope. Only spells actually cast from preparation. Not even scrolls, potions, or any other magic item.

Otherwise, a ring of three wishes just became a ring of six wishes.

Thak you.
Can you give some reference in the rules for it ?

Share Spells: At the paladin's option, the paladin may have any spell cast on him or herself also affect her mount. The mount must be within 5 feet. If the spell has a duration other than instantaneous, the spell stops affecting the mount if it moves farther than 5 feet away and will not affect the mount again even if the mount returns to the paladin before the duration expires. Additionally, the paladin may cast a spell with a target of "You" on the mount (as a touch range spell) instead of on herself. The paladin and the mount can share spells even if the spells normally do not affect creatures of the mount's type.

Boots of speed do not cast a spell.

Spell completion items act the same way - they are the same as casting a spell - they even can be interrupted as a spell can be.

Potions, rings, etc. are not shared because they don't cast spells.
