Are you doing a lot of traversing hillsides? If you are, your snowshoes may be sliding sideways. This will make you use muscles differently than you're used to and will contribute to groin strains. I would suggest some snowshoes with an aggressive heel crampon (as well as the toe crampon) or some shoes with a serrated side, like the MSR brand. MSRs tend to be a bit heavy, and a bit pricey, but they are the best at controlling sideslip.
