I use Speedcross for shorter events but as I am heavy footed I find they don,t have enough Cushioning for the Spine. Hence my use of XT Wings. The soles of your feet are going to take a real pounding. Any feel the ground fell type shoe will probably be to thin.
Using two pairs of insoles and two pairs of sox helps.
Whatever you choose they must be a shoe that never gives you blisters. This should be your highest priority. The grip on the sole is also a consideration . If you use Solomons then go for ones with" Contragrip" soles. I found this type great on wet slabs , ice , mud and stones.
Avoid any shoes designed by race winners which are even lighter than last years model. You want a Ford Focus on your feet not a Ferrari!
Two potential problems with Hokas: They are wide and can twist your feet on frozen churned up mud. Secondly how well do they grip on ice?
Somehow I doubt we will get the same conditions as in 2014 where soft bog was good for Hokas.
Anyone just reading the 2014 blogs will have got only one version of the race. Compared with 2013 ,2014 was tropical ! It never got cold or really windy
. To some extent you need to save your final Kit choices until the last moment. I suspect that some of the 2014 Challanger finishers could be in for a shock if we get snow and ice like the first two years.
If you do go for Hokas then put a pair of conventional shoes in your drop bag.
