Heat issues in sockets

Steve Middleton

I am in my early 50’s for 10 years I have been a very active above knee amputee.
I presently use a heat moulded thermoplastic suction socket, skin fit with no liner. To don the socket, I use the dry pull sock method. I do not require a belt even during high activity.

I cycle both road and mountain bike’s extensively and for the most part have very few issues on longer rides. Perspiration has not been a concern because I can drain the socket of moisture through the vacuum valve. Extreme heat, for example a climate of plus 86 deg F (30 deg C) and humidity does create great discomfort and redness then some swelling. Thus cooling is an issue.

What ideas or suggestions do any of you have for a way to keep this socket cooling during an activity period?
Is there possibly some new device / materials for such an application?

I do not wish to start wearing a sock or liner and realise some of these now have Thermodynamic properties.

I will post your responses.

Many thanks

Steve Middleton Ak amputee
