Solid Stability Shoe

4/5

Overall

Not the shoe you desire, but most likely the one you need. Quite comfortable and well cushioned with good support. The only downside is the bad breathability, sweaty feet in hot weather.

Saucony Guide ISO

3/5

Overall

I have run in Saucony Guides since the Guide 4 and never had any problems with them. The Guide ISO seemed to fit narrower in the toe box than previous models, causing some pain/tingling in my pinky toes. I also noticed my wear pattern was different on these compared to previous models. I wore the outer part of the soles down instead of the center like I normally do. I did like the fit and material of the ISO uppers. I switched to the Rides after this model to see if my wear pattern would be different. I went up a half size in these compared to my previous models as they seemed to run smaller.

Great shoe, only one qualm

5/5

Overall

I've bought two pairs of the Guide ISO , both of which I wear several times a week, and absolutely love them. Went to a shoe store looking to change shoes, put it on, and immediately knew it was the one I wanted. Love the way it looks, love the combo of support and cushioning it has (although everyone's needs vary), and just think it's an all around great shoe. The only reason I didn't give this a 10/10 in everything is that on the first pair I bought, the backing of the inside heel of the shoe wore away within the first 60 miles, so now there's a hole on the inside where my heel is rubbing up against the heel counter and the edges of said hole, which can cause blisters if I don't wear a bandaid to prevent that from happening. This only happened on my first pair, however. I've had my second pair for a month and have already put ~250 miles on them and they show no signs of wearing in the same way. Great overall shoe, just not sure what happened with quality control on that first pair.
