A dream!


I love these shoes. They feel a little bit snug on top at first because we're so use to having laces. But I quickly got used to it. The cushion is perfect, they're easy to get on and off and there's no concern about them coming off during activity. I've been wearing these as a daily shoe to work since I broke a pinky toe and the space has allowed my toe to heal. I can easily pass these off as a dress shoe with dress pants!

The most comfortable shoes ever!


As a Topo ambassador, I was very excited to get this shoe. After receiving it, the excitement is still going strong. A low profile, zero drop midsole that still has a soft cushion and high amounts of flexibility make it great for doing yoga and core work at home. The unique velcro strap provides enough support in the upper that you can run in it or do some weights at the gym. But in all honesty, it makes the perfect casual, wear all day shoe. I wear mine to work most days and they look fine with business casual. Perfect shoes when you're going to be on your feet for extended periods.

COR- the do it all in one shoe... shoe


What an interesting shoe. The shoe looks a little strange, IMO, but performs incredibly. I’ve had the COR a little over a month, and have run in them, lifted weights in them, but they have found their niche as my day to day Work shoe. They feel great as a running shoe as they feel a lot like the ST-2. They perform well as gym shoe, as the uppers structure allows for comfort but is snug enough for lateral movement drills. But mine are now my work shoes. I wear a uniform at work and the COR are just inconspicuous enough in the all black to remain unnoticed. I would usually wear a boot to work, but the upper of the COR has proven that it is durable enough for my work activities. I really enjoy the little toe bumper as well. They are light weight and the upper allows for some nice air flow in warm conditions. I’m very happy to have these as my work shoes, and think that they helped me recover from a 100 miler, as my feet didn’t have to be stuffed into a boot for 10 hours a day.

My Go-To Pair


I absolutely love them. They are my go-to pair when I’m just out and about and when I hit the weights. They are extremely light and comfortable. And at my old age, the velcro fastening is a bonus.

Best shoes ever


These are the best training . Best everyday shoe. I’m a trainer at a gym and wear nothing but these shoes. I think it’s a mistake to get rid of this shoe.

Please Recontinue These!


So I don't actually use these for the gym; I use them as an everyday shoe for work and casual wear. After running in Topos every morning, going to work in my narrow toebox shoe was miserable, so I needed something subtle-looking but still just as comfy as my Topo runners. I gave these a shot, and they work wonders. All the roomy toebox-ness and snug heel-fit of my running Topos, but breathable and easy to slip on and off when I loosen the strap. Being able to work in a comfortable zero-drop shoe is also great for helping me adjust to lower drop running shoes. Topo, for the sake of other potential users out there, please keep making these!
