Superfeet Unisex FLEXmax Athletic Insole

I bought these because my new GEL-VENTURE 8 EXTRA WIDE trail runners had zero arch support. I saw another reviewer that has success with this insole in Asics, but I have the extra wide version. The insole appears to be the same width as the stock insole and the thickness at the forefoot is very close, 1mm less according to my calipers. These are a foam insole somewhat like what was in the Asics stock, BUT have an arch, a heel cup and a semi rigid (firm but flexible) heel/arch cradle. I have very high arches. These are a medium arch but we’re perfect because the shape of the shoe curves up and is snugger in the arch area. If I were to have gotten a true high arch insole, the shoe would have been too tight on top of the foot. I suffer from plantar faccitis and heel spurs. With the stock insole my heels hurt within 4 hours of wear mainly due to lack of arch support, but I otherwise loved the shoe. These solved my problem immediately and did not change the fit of the shoe. I also tested these on my new Danner mountain 600 hiking boots. The stock insoles in those run a little long and I have had some trouble finding a suitable replacement with enough arch. I wear a size 12 and this size fits though 13. They fit the Danners perfectly with NO trimming. Thickness are very close again so no change in the fit. I have an upgraded Danner insole coming but think I may send back and order another pair of these.
