Road shoe so.e delamination

So today I am racing in the weekly Waratahs Crits, enduro event so 90 minutes. I win the race after a sprint finish , roll back to the car and the sole of my shoe slides off :face_with_raised_eyebrow:…

  1. WTF , if that happened in the sprint I would be on be eating road

  2. Is this thing ? Shoes are probably about 6 years old but only used on occasional Sundays and of all my cycling stuff get looked after the best ( in a bag with wooded shoe inserts and kept inside)

  3. Do I even try to get these repaired, would I ever trust them again ??

Yep, I’ve had it with old MTB shoes. They started peeling from the heel and then they finished up ripping the sole off. Different brands use different glues with varying results. Didn’t bother getting the sole glued, I don’t feel that I could trust them. Often the glue goes yellow, which suggests the glue is degrading. Time for new shoes I think.

OH… that happened to me with a pair of old Giro mtb/gravel shoes, I ripped the sole right off bunny hopping a drainage channel. It finished with a very lucky save, my heart in my throat and a bodge of a fix to end the ride with bits and peices of everyone’s repair kit. When my foot released from the pedal it took a few seconds for my brain to catch up with what happened. Scary.

I had this happen with a pair of well-loved road shoes. Clipped in and on the first pull up, the upper came clean off. And I’m not even that strong!

I felt pretty smug for having a small roll of gorilla tape with me, so I could repair the shoe enough to ride home on it gingerly.

Also, to answer question #3: no, I wouldn’t try to get them repaired. Uppers are glued to soles under high pressure with specialized equipment. Some cobblers will have this equipment, but not many. I definitely wouldn’t try it at home.

Will you trust new shoes more? I’d try gluing them back together using Shoe Goo or Barge Cement. Relegate them to casual rides if it makes you feel better.

Probably worth contacting Sidi. Who knows they may offer to replace them or at least a discount on a new set of shoes :person_shrugging:

Agree, I only use them for Crit races so think they are definitely retired

I’ve had that happen to some Sidi mtb shoes also after about 6 years.

I’m glad you found out after the sprint and not during it

Update : As suggested I wrote to Sidi .. “ materials have a lifespan depending on care, storage etc …… it’s not indefinite…” also nicely offered 20% discount on a new pair

So , got me thinking , with no way of telling externally that the glue was about to fail should soles have secondary attachment method to avoid catastrophic failure ? .

Looking at some other shoes I have with carbon soles (glued) they have a toe cap that wraps around the bottom of the sole on the front …. would this keep the sole in place when the glue fails?…

Other shoes probably wear out before the glue fails so not an issue, but for some shoes (race day only) the shoe “looked” in great condition but the glue had exceeded its life. There was a single nail at the back of the sole plate but no secondary attachment method at the front ……
