The Karhu Synchron 2020 is the most luxurious yet.

Cushioned by an AeroFoam Nova midsole, the Synchron delivers a plusher ride than traditional EVA foam compounds. Designers paired the AeroFoam with Karhu’s signature Fulcrum technology, which provides smooth transition and helps runners keep their momentum moving forward.

Karhu built the Synchron 2020 with the help of more than 100,000 3D foot scans taken through Fleet Feet’s fit id outfitting process. The scans help ensure the best possible fit, so you can run in comfort.

Game changer!!

These shoes have been an absolute game changer for me.. I work 10-12 hour days 5 days a week on my feet and prior to this purchase I felt like I had been hit by a truck by the time I got home from work.. since I started wearing these to work I haven’t felt a quarter of the usual back and feet pain that I’m used to. In fact I haven’t worn a different pair of shoes to work since! I plan on coming back and purchasing this shoe in different colors. Thank you guys for getting me into this shoe!

I went into a Fleet feet store for the first time and I was amazed how much attention and detail that they gave me. I bought a pair of Karhu and was amazed how well they fit. Excited to get back into walking/running again and looking forward my 1st 5K

This shoe fits better than

This shoe fits better than probably any tennis shoe I have purchased at Fleet Feet. I've worn it to walk in each day for about 2 weeks. Yesterday, the shoes started making a squeaking sound with each step. The shoes have never gotten wet. The sound is kind of driving me crazy. Is there a reason my shoe would be doing this? Meagan helped me so much with this purchase- thank you Meagan.

Online order, quick delivery

I ordered through the online system for the first time. I already had a pair of the same brand of shoes, so I knew they would fit. I did not see an obvious way to select curbside pick-up (which would have been my preference). The shoes arrived within a couple days, however, so I was satisfied. I also appreciated the personal, hand-written thank you note that came in my order.
