To any Altra Lone Peak users out there: How important is it to use arch support inserts in the Altra Lone Peak 4.5 trail shoes ? The salesperson at REI indicated that it is quite important for arch support to use them since they are zero drop and don’t provide arch support on their own. but I have trouble sizing the shoe with inserts: my sizes (11.5 or 12) both feel very comfortable without inerts but much tighter and less comfortable with them, and sizing up the shoe farther than size 12 is not an option I want to consider : then too much room in the toebox . My feet are generally healthy and sound I have no foot problems (arches , etc) wearing a wide variety of shoes , and walking around in them in the store without inserts feels perfectly comfortable.
Are inserts something that Altra users just do, or don’t do, or is it optional, varies from person to person?
