Resolve Tree:

KEYSTONE: Guardian is the best keystone for Braum. It has synergy very well with his w ability. As soon as you use it the Guardian ability will proc giving you Guard that lasts for 2.5 seconds regardless of distance. This means that if you w to your ally you can move as far away from them as you like for 2.5 seconds and still get the shield from Guard. This means that if you jump to your champ, move forward and pop your e. If you take damage from enemy champs (including on your shield) you and your ally will gain the shield and movement speed.

FIRST TREE: In this tree you can go either Font of Life or Guardian. I like both just as much.
Font of Life: This Rune works well with your q so if you can hit it frequently it is a great rune. It will also help your ADC sustain a lot longer in lane. It also is awesome for a multi-champ knock up on your Ultimate. It will give your whole team a good bit of healing.
(Side note: If you take Font of Life you have the cool option of building Ardent Censor because this rune will proc its passive)
Bone Plating: If you struggle to hit your q take Bone Plating as it works great with your e and is pretty easy to get good use out of.

SECOND TREE:
Here you have a choice between Second Wind and Conditioning. Second Wind will be better for the laning phase while Conditioning will make you more of a tank and is better in the late game. Because of the current pace of the game I suggest you take Second Wind.
Second Wind: Pretty self explanatory rune here. Nothing too exciting but it will make it easier to walk up to minions to use your Relic Shield.
Conditioning: Again nothing too exciting here. You will get a pretty nice boost at 10 minutes but it makes laning more difficult. Main reason I suggest you take Second Wind.

THIRD TREE:
Again a couple of options here. These are the runes that feel the weakest. You can really take any of the three. Play around with these and find which one feels best for you.
Unflinching: I will suggest you play with this rune first. Unflinching will be a good replacement for not taking Mercury Treads and will make you more successful at escaping. If you plan on taking Treads during the game because of the Enemy Champs as I will outline when I talk about boots then go for one of the other two runes.
Overgrowth: This is the next best rune in this tree. If you do end up taking this one I would suggest you take Bone Plating and Conditioning and then focus on building Health Items over Tank items.
Revitalize: This Rune will only really work if you play with Font of Life and Second Wind. Don't use it if you are not using those runes.

Inspiration Tree:
Not much other choices here. Footwear and Biscuits are the way to go. Future's Market is a possibility but Biscuit Delivery is overall better mainly because of the bonus mana.
