Not good

Bought these for my son for his park runs but he complains pain in heel after he runs in these shoes even after running short 2k distance. These are advertised as running shoes but doesn’t seem good for running.

Great shoe with a lot for the price.

Padded ankle, lightweight, cushioned sole. Daughter loves running in them and likes the bright colours. Not raced in mud yet so soles may be a bit 'shallow' but great around trainer so far.

Excellent pair of trainers for the money

Not very hard wearing

I’ve had many pairs of trainers from decathlon for my children and generally they have been great value and durable but I have been very disappointed with these ones. I only bought them about 6 weeks ago and the soles/treads are already badly worn, and they are wearing thin and badly scuffed. I do have two quite sporty and active boys but would still expect trainers to last more than a few months.

Hello Natasha,

Hope you are doing well.

I am sorry to hear that these running shoes did not meet your expectations. Please feel free to bring them back and we will happily swap them for a different pair.

Hope it helps!

Kiprun Kids

Very good quality running shoe, excellent!

Additional Product Information


Outer sole of: 60.0% Ethylene Vinyl Acetate, 40.0% Synthetic Rubber ; Upper of: 70.0% Polyester Cationic, 30.0% Polyurethane ; Lining and sock of: 50.0% Polyester Cationic, 50.0% Ethylene Vinyl Acetate

What's drop?

The drop of a shoe is the difference in sole height between the forefoot and the heel. The shorter the drop, the more natural the foot movement for running, reducing ”biomechanical” action that can cause injury. The drop of these KIPRUN FAST shoes has been reduced to 6 mm to respect your little one's natural stride!

Take a look under the sole?

The sole has flex grooves for easier heel-to-toe transition when doing sport. The hard-wearing rubber half-sole prevents young athletes slipping on wet surfaces!

Did you know? kids and adult shoes don't have the same fit.

Junior athletics shoes are specifically designed for kids' feet. For the same size, a kid's foot is slimmer and less voluminous in the shoe compared with an adults. Give your young growing athlete space so they don't feel restricted when doing sport. If an adult chooses a shoe designed for kids, their foot movements are restricted, which has a direct impact on the body!

Product testing

Driss, our engineer, field-tested these shoes with a panel of 12 kids aged 8 to 12, at an athletics stadium during 2 hours of activities, including running, jumping and throwing. All the kids liked these shoes for their cushioning, comfort and propulsion.Our products are also tested for durability over time before going on sale.
