Kiprun Kip Summit Max Review: Max Cushioning for Trails and Ultras

Introduction

The Kiprun Kip Summit Max is a max cushioned trail running shoe built to handle a wide range of distances and terrain. It is aimed squarely at ultra marathon events thanks to a very tall stack of cushioning, but it also works well as a day-to-day trail trainer. At £120 in the UK it is notably good value, while the $150 US price is closer to par for the category.

At 290 g (10.2 oz) in a UK 8.5 / US 9.5, with a 6 mm drop and a heel stack of roughly 38 to 38.5 mm, it is a big shoe on paper. In practice, it feels more versatile than its size suggests.

Design and Upper

The upper uses a mesh construction with a reinforced toe box to protect your toes on rough ground. Padding is generous, particularly on the tongue, which delivers a very secure, padded hold around the top of the foot. There is arguably a lot of tongue going on here, and that creates a slightly oppressive, heavily padded feel on top of the shoe.

Around the heel, the picture is more comfortable. There is lots of fabric and padding at the collar and back of the shoe, and crucially there is no big stiff internal heel counter. That flexibility makes the back of the shoe feel softer and less rigid than the padding suggests, and it helps the foot stay put on uneven terrain without feeling restrictive.

Fit and Sizing

The tester went half a size down from normal UK size, which is typical for Kiprun shoes on the road. For this trail shoe, though, sticking to your normal size may actually be the better call. Trail running benefits from extra room around the toes, especially on descents.

If you normally go half a size down in Kiprun shoes, that should still work. If you are looking at this shoe for ultra marathons in particular, a roomier fit in your regular size may suit you better, particularly on longer, hotter days when the generous padding around the tongue and collar becomes more noticeable.

Midsole and Outsole

The midsole uses Kiprun’s Fast Tech Plus foam, a supercritical ETPU foam that has performed well on other Kiprun shoes this year, including the Kipstorm Tempo. The foam forms large sidewalls at the heel that your foot sits within, which is why the shoe looks even higher stack than it is, and it adds meaningful stability.

Underneath is a Vibram Megagrip outsole with 4 mm lugs. The lugs are broad and quite widely spaced, so the shoe feels comfortable on flatter, harder surfaces including roads, while the 4 mm depth still gives enough bite on softer ground.

Ride and Performance

The Fast Tech Plus foam does not feel quite as bouncy and lightweight here as in other Kiprun shoes, largely because of the sticky outsole and the less stripped-back upper. Even so, there is a clear spring from the first step, and it retains that bounce deep into long runs. A 10-miler and a 15-miler, both done the day after heavy 20-mile workout sessions, felt just as good at the end as at the start.

The springiness carries over to well-groomed trails and even uneven ground, which is not always the case with big trail foams. A mild rocker helps you tick along on tired legs, and despite its size the shoe feels fairly nimble on uphills, including narrow, uncertain footing.

On descents, the shoe delivers plenty of protection and reliable grip, so runnable hills can be bombed down without feeling the impact through your legs. On tighter, twistier descents it demands a little more care, since the big platform can make foot placement less precise. Across grass, mud, hard-pack trails, gravel, rooty single track and rutted mud, grip was very good, and the platform felt stable and supportive. Easy and recovery runs are where it excels: on very tired legs it gives a bit of bounce back, so you finish feeling better than you started.

Value and Verdict

The Kip Summit Max is a really strong trail shoe that should appeal to a broad range of runners. It is marketed as a max cushioned ultra shoe, and it will likely do that job well, but it has plenty of scope as a daily cushioned trail trainer. Think of it as a max cushioned road shoe with better grip, added stability, and the ability to handle trails where a road shoe will not cut it.

Compared with the Hoka Speedgoat 7, the Speedgoat offers a firmer, more nimble ride for technical mountain trails and is a little lighter, but the Kiprun has a comfier and livelier midsole, is much cheaper in the UK and similar or slightly cheaper in the US. On hard, rocky trails, that extra comfort and support is genuinely felt.

At £120 in the UK, this is exceptionally good value for a durable, fun, versatile trail shoe that can handle most UK terrain aside from really deep mud or very slick fells. It is the kind of shoe that works for winter forest runs and stays comfortable on harder summer trails. No significant problems came up during testing, and it is easy to recommend to anyone after a cushioned, grippy everyday trail shoe.

Conclusion

The Kiprun Kip Summit Max combines a lively supercritical foam midsole, dependable Vibram Megagrip traction, and a secure padded upper in a package that works for ultras and daily trail training alike. UK pricing makes it a standout value pick, and even at the higher US price it remains a well-rounded, comfortable option for the majority of trail runners.
