Great quality, very comfortable!

The shoes are super comfy and just look good. White is always tough to keep clean but that is the case with all white shoes..

My new favorite sneaker brand

I never post reviews, but I think this company deserves it.

I bought these shoes via Opumo about 1 month ago. I bought them because I loved the look from the side as it makes these shoes stand out from the dozens of other "minimal sneakers". I contacted Jak's customer support to enquire about the sizing, and they responded quite fast.

The grey has a "blueish" hue, which I was a bit unsure about at the beginning, but now I like it.

In the past month I've worn them 2-3 times per week (min 7 hours each time) and I'm surprised by how well the leather is holding up. I have another pair of full grain sneakers (Svensson), which I've given them the same "beating" as these Jak shoes. The Svenssons had creased so badly after 1 month, and even started to show defects on the leather after 1 week. The Jaks, 1 month after look pristine, and the creases on the leather don't look bad at all.

I would have liked to have Margom soles on these ones as I hear they are extremely durable. But the soles are holding up really good! Only time will tell how good :)

The shoes are surprisingly lightweight, and comfortable. Although they took me like 1-2 weeks to break in.

The inner sole, although not removable, is quite "cushiony" and comfortable.

The only 2 things I dislike is that the laces are not that great (I'll have to buy some new ones). Also, the metallic eyelets are staining the laces in black (probably due to oxidisation), which ruin the look on the shoes as it makes them look dirty when in reality they're not.

Overall, awesome job guys! I'll keep coming back for more :)
