Because of your activity level and bone spur I suggest the X1 Blade Reverse Morton - gives you more room in the toe box of your shoe and provides enough rigidity to limit 1st met motion.ClydeContact Name: Charlotte MacNxxxxxxxPhone: 403-XXX-44X7 Email Address: firstname.lastname@example.org Comments or Questions: Have arthritis in 1st metatarsal joint with bone spur. Quite limited range of motion in big toe. Foot doctor suggested X1 blade. I am trying to figure out difference between -X1 Blade turf toe and hallux rigidus- and -X1 Blade with Reverse Morton's Extension for the Treatment of Hallux Limitus, Hallux Rigidus with Bone Spur, or Sesamoiditis-. I am a very active athlete. Main sports are trail/mountain running and orienteering - so frequently running on uneven surfaces. Will definitely try an X1 blade - just need some help to pick the right one. Thanks!
