Perfect fitting shoes for wide feet

I have wide feet and these shoes fit me perfect.

I sent the shoes back for a refund, as unfortunately just don’t fit my foot shape.

Karhu makes great shoes that fit well

Normally I use the Fusion shoes, but I wanted to try the new 2.0 Synchron.
For me it feels like the Fusion are the typical high performance running shoes whereas the Synchron is best for Low heartbeat running, or even walking.

Very good !

Fits like a glove

Ordered the HIGH VOLUME version. And am not disappointed. I do have wide feet in the front and a high arch. Both are handled by the hivo very well. Problem with running however, is. I’m a mid/forefoot lander. These shoes are made for heelstrikers. Running in them makes a lot of noise running on pavement and I do have to change my landing to handle it. I imagine heelstrikers don’t have this problem. I do use them primarily for walking now.
