Customer Reviews Newton Running Isaac

I absolutely LOVE newton running shoes - this will be my second pair. I had a professional running analysis done and these were one of their suggestions, and I am so glad I picked them. They do take some getting used to, but I really feel like they have improved my gait, as well as cause absolutely no knee or hip pain which I had with other brands, and the toe box has decent space. They are also much more durable, built to last a full year for a moderate runner like me. So well worth the price! For sizing I always go up in running shoes, so with these I am a 10, even though in regular shoes I wear an 8 1/2.

I just tried running in these shoes today. I was going to just run 10 miles today because I am training for my marathons. I ended up doing 13.1 miles instead because these shoes are great. I would also like to note I didn't have blisters afterwards like I normally do and no foot pain either. I will keep buying these shoes for sure!

Love them

These are the best running shoes I've ever owned. After having plantar fasciotomy surgeries on both feet, I needed something with great support. These shoes train your feet to run at the front by reducing the ability to heel strike. This is my second pair, and I love them!

The Lady Isaac is a great shoe for those doing run/walk interval training. You get the light weight and extra pep of the performance Newton's, without the lower heel, which makes the walk portion easier. Like with other Newton's, the shoelaces are too short.

I walk 20 miles or more each week so a comfortable, supportive shoe is critical. I've worn a lot of different brands and styles and this is by far the best for me. As the video salesman says "try it". I don't think you'll be disappointed.

I ended up returning these and getting the Issac S instead; I could feel my foot pronating a little with these shoes and needed the added stability of the "S" model. Other than that, the shoes were well made and comfortable. I determined proper size on the Newton website where you can enter your existing running shoe and size and it will tell you what size you need... it suggested that I go up a half size from my normal running shoe size and that was right on. I am now using the Isaac S shoes for walking and running and they are great. The mild plantar fasciitis symptoms I was having have disappeared since I switched to the Newtons.

The best running shoe I have ever had! Well worth every penny. Just wish there were more color choices for this style For sizing go to the Newton website for help. You can put in the size of your current running shoe and brand and they will show you what size you need in the Newton shoe you choose. I needed to go up a half size. I did need to add my Superfeet insoles but that's usually the case with most athletic shoes.

These are so awesome, very lightweight and very comfortable. I did so up a 1/2 size and they fir fine

I was worried that since I am a beginning runner these shoes wouldn't work for me. But they work great! It took a couple of runs to break them in, but now they seem to work perfectly. The only downside I have found to these shoes is that they are not very comfortable to walk in if you need to take a break. But running in them is a breeze!
