The Brooks Ariel 18 / Brooks Beast 18 and the Brooks Adrenaline GTS 18 are both stability running shoes, but the Brooks Ariel 18 / Brooks Beast 18 is a motion control running shoe, while the Brooks Adrenaline GTS 18 is not but comes close to being one.

ADVERTISEMENTS

The Brooks Ariel / Brooks Beast and the Brooks Adrenaline GTS used to look a lot like each other and share many of the same features.

However, with running shoe manufacturers moving more towards seamless uppers and more comfortable running shoes, the Brooks Ariel / Brooks Beast and the Brooks Adrenaline GTS started to show more individualism.

The uppers of the Brooks Adrenaline GTS 18 The preceding link takes you to Amazon.com and the Brooks Ariel 18 / Brooks Beast 18 are similar in that they don't come with many stitches in them.

The Brooks Ariel 18 The preceding link takes you to Amazon.com / Brooks Beast 18 The preceding link takes you to Amazon.com has a stitched-on toecap and some stitches in the saddle, but most of its upper consists of mesh and no-sew overlays.

The Brooks Adrenaline GTS 18 has stitches in its saddle, but most of its upper also consists of mesh and no-sew overlays.

However, the overlays are broader on the Brooks Ariel 18 / Brooks Beast 18 and cover the midfoot better than those on the Brooks Adrenaline GTS 18, which has overlays located more around the heel.

Therefore, the Brooks Ariel 18 / Brooks Beast 18 is likely to give you a more secure fit than the Brooks Adrenaline GTS 18.

The forefoot of both running shoes has been kept pretty open, although the Brooks Ariel 18 / Brooks Beast 18 has no-sew overlays running along the upper edge of the midsole around the toe box.

However, because the bunion window is still pretty open, you should be able to get a good amount of comfort in the toe box of both running shoes.

The Brooks Ariel 18 / Brooks Beast 18 has an external heel counter at the back, while the Brooks Adrenaline GTS 18 only has overlays in that area.

All in all, the Brooks Ariel 18 / Brooks Beast 18 delivers more support through its upper than the Brooks Adrenaline GTS 18, which is not surprising.

The Brooks Adrenaline GTS 18 and the Brooks Ariel 18 / Brooks Beast 18 make use of the same type of midsole material, but their midsoles look slightly different.

The Brooks Ariel 18 / Brooks Beast 18 comes with a full-length crash pad on the lateral side, something which previous versions of the Brooks Adrenaline GTS used to have.

The lateral side of the midsole of the Brooks Adrenaline GTS 18 now only displays a good amount of segmentation.

The Brooks Ariel 18 / Brooks Beast 18 is meant to deliver a cushy ride, and while the Brooks Adrenaline GTS has not been very cushy in the past, the Brooks Adrenaline GTS 18 also delivers an overall cushy ride to runners.

Both running shoes provide a good amount of ground contact so are capable of delivering smooth heel-to-toe transitions and some stability in addition to the stability they deliver on the medial side of their midsoles through the use of a medial post.

The medial post is long in both running shoes, and while they are both being reinforced by midfoot shanks, the Brooks Ariel 18 / Brooks Beast 18 is the one that has a midfoot shank that hooks up into the medial post under a big part of the heel.

The midfoot shank of the Brooks Adrenaline GTS 18 is more discrete and covers an area just under the midfoot.

Therefore, you can expect the Brooks Ariel 18 / Brooks Beast 18 to deliver a much stronger degree of pronation control than the Brooks Adrenaline GTS 18, which is expected of these two running shoes.

The rubber outsoles was another area where these two running shoes were quite similar.

They still display a lot of similarities by having small rubber pods, a good amount of segmentation and separation, and similarly running flex grooves in the forefoot.

The Brooks Adrenaline GTS 18 is not a very flexible running shoe and neither is the Brooks Ariel 18 / Brooks Beast 18, but stiffness adds stability to a running shoe.

Where they differ is in the shape of the running platform itself. This is broad under the Brooks Ariel 18 / Brooks Beast 18, while the Brooks Adrenaline GTS 18 displays the shape of a normal foot.

This is a good indication that the Brooks Ariel 18 / Brooks Beast 18 is more suitable for runners who have flat feet.

The women's version of the Brooks Adrenaline GTS 18 weighs approximately 8.3 oz (235 grams), while the Brooks Ariel 18 for women weighs approximately 11.8 oz (335 grams).

The men's version of the Brooks Adrenaline GTS 18 weighs about 9.7 oz (275 grams), and Brooks Beast 18 for men weighs 13.3 oz (377 grams).

The Brooks Ariel 18 and the Brooks Beast 18 are much heavier running shoes than the Brooks Adrenaline GTS 18 for women and men.

Therefore, the Brooks Ariel 18 / Brooks Beast 18 is more suitable for heavier runners who can handle the weight of the running shoe.

The Brooks Adrenaline GTS 18 is good for medium-sized moderate to severe overpronators who need a lot of stability and support but not to the degree that a motion control running shoe would deliver.

The Brooks Ariel 18 / Brooks Beast 18 is good for heavier and bigger severe overpronators who need tons of stability and support and lots of pronation control.
