Review:
Spenco
The Polysorb Insole by Spenco is an excellent for people seeking firmer support and motion control. It features a heat mold foot bed for a custom fit without breaking the budget.
Easy to use, just trim the insole to fit into shoe and place in a preheated over for two minutes. Quickly insert insoles in shoes and insert feet, with socks on, tighten laces, and wait for ten minutes.
I found these high performance insoles to have incredible support, both in the arch and heel making them great for any high impact activity. The improved control helps reduce pronation and supination.
I tried them with a pair of boots that had very little to almost no previous breaking in and found that with the insoles they felt like they fit like a glove and gave me the support I needed.
