38 miles in ?

3/5

Overall

I’ve been running off and on for years and my last shoes were a Guide 7s. Those were miled out a long time ago, so it was time for some new ones. Got the Guide ISO 2s and they felt good enough to be recognizable to my last. I chalked up the stiffer sole to them being new and started putting miles on them. I run hills on pavement and got 38 miles on them. When I looked at the sole for the first time to pack them for a trip, I noticed the rubber was gone at the ball if the foot and I’d chewed into the foam already. Super bummed. I’m a mid/forefoot striker, but 38 miles doesn’t cut it. Sadly, I’ll be returning them. I’m a huge Saucony fan, and these shoes have great ratings, but they didn’t work for me.

Firm but stable. Moderately flexible, could use a touch a more flex but overall, standard stability shoe.

Good shoe overall. I’ve been in the guides since the guide 7. I liked the shoes better before saucony went to the iso fit.

5/5

Overall

I have run in this shoe for about six months now, and I have to say, I am very pleased. The stability of the shoe keeps me in proper alignment, but more impressively, it does it without feeling intrusive or heavy. I have run tempos, 200s, and long runs all in this shoe and have felt confident in the shoe all the way through. The ride is firm but not hard and allows me to feel fast even though I am cushioned and supported.
