Running shoes available on the market are categorized into two groups. The first group has a firmer medial post while the second doesn’t have it.
The first type of running shoes are known as stability shoes while those without the medial post are neutral.
Stability shoes on the market also vary.
Whereas some have a smaller medial wedge, others feature huge posts running from the forefoot to the heel. However, some models don’t have a wedge.
Stability running shoes also vary in midsole softness, shoe weight and the footprint of the outsole.
Due to availability in various models and features, stability shoes also come in different categories. Some feature “motion-control” attributes, meaning the outer midsole is more compressible that the inside.
The second category of stability shoes resemble lightweight trainers or neutral shoes in terms of feel.
They don’t have imminent hardness due the presence of a media post. Stability shoes correct over-pronation and reduce inward foot roll.
You can see the overall differences between Saucony & Brooks here, in this detailed article.
Although some brands say that stability shoes are only for over-pronating runners, the choice of these running shoes can depend on personal preference. Whereas some runners love the firm medial post sensation under their foot, others don’t.
And, as mentioned above, stability shoes aren’t all the same.
Stability shoes can be categorized under three sub-groups. The first kind are the most popular due to mild support features for daily training. The medial post is less intrusive and thus you may not feel it.
The second category offer optimal support without dimensions and weight being a consideration.
They feature an over-sized medial post, high weight and extremely wide footprint of the outsole for the most stability in running shoes.
The third category of stability shoes are lightweight trainers designed to offer mild stability.
They feature midsoles fitted with small medial posts to support fast training and runs. In this article, we review Saucony RedeemerISO 2 vs the Brooks Beast 18 to help compare the two running shoe product lines.
The Saucony Redeemer ISO 2
Is designed for runners with flat feet or those who need custom orthotics.
The stability shoes weigh 12.5 ounces and competes with other top brands such as the New Balance 1260v7 weighing 11.7 ounces, the Mizuno Wave Horizon 2 weighing 12 ounces, the Asics Gel Kayano 25 weighing 11.5 ounces, and the Saucony Hurricane ISO 4.
The Redeemer ISO 2 is attractive just like any other conventional stability running shoe. The ISOFIT system gives it premium construction in terms of look and feel. The soft upper and padded heel cup are made from soft textile or foam material for increased comfort.
The sole and insole are flat without a plastic shank in the midsole. However, the thick sole offers torsional stability.
The heel is wide and your foot may slip off easily if it’s not ideal for your size. Tightening the lacing system may not help, only tightening the midfoot area.
Locking laces have proved to be an effect way to tighten laces which helps with stability.
The soft upper is warm, high quality and comfortable. The gait is natural and the inside of the shoe lacks seams. The EVERUN layer above the midsole cushions your landing to reduce impact.
The Redeemer ISO 2’s sole unit features a complete EVERUN layer beneath your feet at the top. The layer features micro TPU pallets in thousands for a bouncy effect, making the soft layer responsive. The midsole integrates a standard foam with a stable medial post for motion control.
The flat outsole has a wide base designed based on the TRI-FLEX technology for increased flexibility and toe-off. This running shoe delivers stable, comfortable rides, gently guiding your strides without restrictions.
Unlike the midsole, the heel is soft due to the EVERUN technology.
You feel the softness of the heel each time you land. However, the running shoes aren’t as bouncy as the Adidas UltraBoost ST’s midsole.
The upper unit features the ISOFIT system, giving it a bootie-structure with an outer exo-skeleton holding the lacing system.
On the outside is a sturdy heel counter made of plastic. The flexible mesh is comfortable without seams on the inside. The padded heel features memory foam for added comfort.
The heel of some runners may keep sliding off, making the shoes uncomfortable for running or walking. This is despite the toe box fitting well into the shoe.

So, what's the Difference?
The Saucony Redeemer ISO 2 provides great support and fast rides for runners with severe overpronation. Brooks 18, on the other hand, provides optimal comfort and pronation control for heavy runners.
Both running shoes offer motion control for big and heavy runners with flat feet. The upper of the Beast 18 and Redeemer ISO 2 have various similarities. They provide sufficient midfoot support.
However, Redeemer ISO 2 features thicker and sturdier overlays with stiches on them while Beast 18 has no-sew overlays on the midfoot area. Therefore, the former offers a more secure midfoot fit than the Beast 18 running shoes.
Even so, the Redeemer ISO 2’s midfoot overlays run further forward than in the counterpart.
Unlike ISO 2, the Beast 18 opens up the bunion window and toe box areas a bit more. Therefore, Beast 18 gives more comfort.
The Beast 18 features a stitched-on toecap for increased durability while ISO 2 has a no-sew toecap. The outer heel counter at the back of both shoes offer additional support.
The uppers of both shoes look-alike, but ISO 2’s offer better support while that of Beast 18 is more comfortable. Both running shoes are padded and cushioned for comfort and support.
However, the midsole in both shoes differ. The crash pad is positioned on the lateral side and comes in a full length in the Beast 18. It also features a long medial post integrated on the side.
ISO 2 lacks the crash pad, but features extra cushioning on the top sole for softer rides from your heel to the toe area. The crash feature beneath the heel absorbs shock to reduce impact.
The midsole crash pad on Beast 18 gives soft rides with better stability than the ISO 2 running shoe. Both shoes support smooth transitions from heel to toe due good contact with the ground. ISO 2 has a long medial post.
The midfoot shank in Beast 18 runs into the medial post for reinforcement, resulting in better pronation control. However, ISO 2lacks the shank and features a triangular medial post that’s positioned at the top of the shoe.
Unlike Beast 18, ISO 2’s outer heel counter on the upper aligns with the medial post towards the midfoot area. Therefore, the running shoes have diminished heel rotation on the upper prior to medial post pronation control.
Unlike ISO 2, Beast 18 is likely to provide better pronation control support. Both shoes feature broad outsoles beneath the midfoot, meaning they’re ideal for runners with flat or wide feet.
The outsoles feature different rubber patterns. ISO 2 has more flex grooves while Beast 18 displays more small rubber pods. Although Beast 18 is more flexible than the ISO 2, both shoes aren’t so flexible.
Whereas the ISO 2 for women weighs 10.5 ounces, Beast 18 for women weighs 11.8 ounces. Beast 18 for men weighs 13.3 ounces while ISO 2 for men weighs 12 ounces.
Both running shoes offer support for extreme overpronation, soft rides and stability for runners. However, ISO 2 has a more secure fit atop being lighter than Beast 18, which offers better pronation control.
Conclusion: Saucony Redeemer vs. Brooks Beast
The Saucony Redeemer ISO 2 has 8mm drop, rolls well across the gait and offers good stability under your foot due to the EVERUN layer.
It’s ideal for long slow runs during recovery. The heel is wide, and toe box small. Opt for it if you’re looking for running shoes to use in summer or spring.
On the other hand, Brooks Beast 18 is ideal for runners with the need for additional stability, support for plantar fasciitis and other heel pain, and overpronation support. Opt for the best stability running shoes based on your unique running needs.
