He started Run Infinity to share his passion for running with the world and has been providing people a lot of motivation and guidance.

This is what he has got to say about the Kalenji Kiprun LD shoes after using them for the Bengaluru Marathon.


Kalenji is a Decathlon’s brand dedicated to running, created in March 2004. At an altitude of 2000m on the high plateaux of West Kenya, a place called Eldoret is the home of the Kalenjins. The name ‘Kalenji’ is a reference to this tribe. They represent barely 3 million people, or ten percent of the Kenyan population. Running has been part of their lives throughout their history, and an inspiration for the Kalenji brand with the motto “Find your rhythm, enjoy your run“.

Kiprun LD Running Shoe – Rundown

Kiprun series has this different categorization of shoes based on the runner profile, called SD (short distance), MD (medium distance), LD (long distance), and Comp (Competitive athletes). The Kiprun LD is designed for runners with mild over-pronation, weighing less than 90 kg. Designed especially for long distances with cushioning and stability, these products are ideal for long training sessions and marathon races.

Here’s a quick comparison on what shoe the folks at Kalenji suggest based on the race you are training for, and your weight, the two key parameters which decide your choice of shoe:

Weight: The shoes weigh 300g for size 43 (my size, though they list it as weighing 325 gm), which is on par with of most of the cushioned trainers out there. Given that the shoes have been created with a marathoner in mind, they are reasonably lightweight, they are not looking at competing with the lightweight trainers from other companies which fall in the 230-300g weight category, which I think is fair.

Stability: The shoe is designed for over pronators, with arches on the flatter side (like me), whose foot rolls inwards as it lands from the outside of the heel to the inside toe. The intent is to control the movement of the foot as it lands. With the Kiprun, this is achieved by having a stiff heel plate at mid foot providing high stability in races.

Cushioning: The 2014 model of the Kiprun LD has significant cushioning improvements over the 2013 model. Included now is a K-RING (an EVA foam insert) in the heel providing 12% more cushioning. The new geometry of the mid sole, combined with a 2mm reduction in drop, also contributes to better shock absorption.

With cushioning and stability, the design intent for these products is to provide an ideal experience for long sessions and marathon races, which makes it an easy choice for runners to choose the right shoe. The Kiprun SD’s for the shorter distances, MD for the medium (half marathon) ones, and LD for the longer marathon run (or for higher weight runners who need the extra stability and cushioning features). Nice!


My Experience with Kiprun LD

I used the Kiprun LD exclusively for training for the inaugural Bengaluru Marathon. The training mostly involved shorter runs of up to 5KM while I was training with my spouse for her Pinkathon Delhi run. The longer runs tapped out at 20K, including a speed session at this distance very early during breaking into the shoe. That run surprised me as the shoe held up pretty comfortable at the faster pace. The front section especially felt comfortable, and unlike other shoes which leave me with some blue (irritated) toenails due to having some longish ones which push against the front end of the shoe.

Final verdict

The race at Bengaluru Marathon went exceptionally well. No discomfort at the front end at all. No blisters on any of the foot (which I have to go through at many races, in spite of the taping). I thought the shoe indeed gave a good mix of cushioning and stability. A personal best time for me in my 10 years of running added to the delight! Post race recovery was very good too. So, a thumbs up from my experience.
