KARHU Running Shoe Guide

Find the right shoe for your run

Every run places different demands on your shoes. A comfortable daily trainer may prioritise balanced cushioning and support, while a shoe for faster sessions should feel more responsive. Trail running requires additional grip, protection and control on uneven surfaces.

This guide compares the current KARHU running shoe collection by cushioning, support, terrain and intended use. Use it to find the model that best matches your training and running preferences.

Start with your type of run: consider where you run, how far you typically go and whether you prefer a soft, balanced or more responsive underfoot feel.

Choose by training type

What type of running shoe do you need?

Your weekly training can include several types of runs. Choose a shoe based on the type of session you complete most often, or combine different models in a running shoe rotation.

Daily running

Daily trainers balance comfort, cushioning and support. They are designed to handle regular training at a variety of comfortable paces.

Recommended models Ikoni 3.5, Fusion 5.0

Long-distance running

Long-distance shoes prioritise lasting cushioning, a stable platform and comfort as the kilometres build.

Recommended models Mestari Run 2.0, Ikoni 3.5

Recovery runs

Recovery runs generally benefit from a comfortable, highly cushioned ride that supports relaxed and controlled movement.

Recommended model Mestari Run 2.0

Underfoot feel

Understanding running shoe cushioning

Cushioning is not only about how soft a shoe feels. The amount and type of foam also influence responsiveness, protection, stability and the transition from landing to toe-off.

Balanced cushioning

Versatile comfort

Balanced cushioning combines underfoot protection with a stable and controlled feel. It is a versatile choice for runners who want one shoe for regular daily training.

Models Ikoni 3.5 and Ikoni ATR

Responsive cushioning

A more energetic ride

Responsive cushioning is designed to feel lively through the transition. It suits runners who want cushioning combined with a more propulsive sensation during everyday training.

Model Fusion 5.0

Maximum cushioning

More protection underfoot

Maximum cushioning uses a higher amount of foam to create a plush and protective experience. It can be particularly comfortable for long runs, recovery sessions and high weekly mileage.

Model Mestari Run 2.0

Trail cushioning should also provide protection and control on uneven terrain. The Ikoni Trail combines cushioning with a rugged construction and trail-specific grip.
