Favorite Running Shoe
I run 4-5 x a week and do alternate my sneakers. However, Lady Isaac's are my favorite ! Customer Service is superior too. Now, if we can just work on getting some additional colors - like pink !!

Resolved My Morton's Neuromas!!
Developed bilateral Morton's neuromas after my last marathon and suffered running for years.
Bought by first Lady Isaacs last year and issue resolved within a few months, finally able to increase my mileage again.
Have bough another pair since then of course and do hope they continue the Lady Isaac for many years to come.

Awesome Daily Shoe
I've been a long time owner of the Gravity for running, but was struggling to find a shoe to wear daily (work, walking around Disney, walking the dog, etc). Then it dawned on me, why don't I see if Newton has a pair made for walking, too? I'm a few days in and I'm obsessed with these shoes. After being used to the heel drop on the Gravity, I wouldn't run in these. You can definitely feel the higher heel and overall heel cushioning/support. But this is what makes them amazing as a day to day shoe. I usually walk about 5 miles a day (if I'm not running) and these have made my feet very happy. Never buying another brand of running or walking shoe again.

Best Running Shoe
Was turned onto Newton Running shoes back in 2012. Bought my first pair of Lady Isaac shoes and fell in love with them. I did not know what I was missing. These shoes supported my foot and gave me a better feel for my form. I was able to run my 1st 1/2 marathon in them without any issues. I am a size 7 but the sales rep told me to go a full size up. Boy were they right!!! However if you are going to run for distance, do not hesitate to go 1 and 1/2 sizes up to accommodate for the swelling of your feet. The new model I got last year is wonderful, however the toe guard started to feel, and I feel like the materials are a little less than par for quality. Perhaps my 3rd pair will be the best yet. We shall see! I definitely recommend this shoe!!!
