Due to my low arches, I need insoles to exercise without pain. I’ve used different ones in the past (most recently Superfeet in my cross-trainers and running shoes) but always had a little discomfort due to lack of cushioning. I’ve been using the Spenco Polysorb Cross Trainer Insoles for the past few weeks and have no complaints. I haven’t tried running with them yet, but will attempt it soon. I also bought a pair for my mom and she’s very happy with them. I usually don’t write reviews, but I just had to for these insoles.
